ROHM launches wide SOA MOSFET for AI servers in compact 5×6mm package

　　ROHM has developed the 100V power MOSFET - RS7P200BM - achieving industry-leading SOA in a 5060-size (5.0mm × 6.0mm) package. This product is ideal for hot-swap circuits in AI servers using 48V power supplies as well as for industrial power supplies requiring battery protection.　　The rapid evolution and widespread adoption of AI technologies have increased the demand for stable operation and improved power efficiency in servers equipped with generative AI and high-performance GPUs. Particularly in hot-swap circuits, power MOSFETs with wide SOA are essential to handle inrush current and overload conditions, ensuring stable operation. Furthermore, within data centers and AI servers, the transition towards 48V power supplies, which offer superior power conversion efficiency, is progressing against a backdrop of energy conservation. This necessitates the development of high-voltage, high-efficiency power supply circuits capable of meeting these demands.　　Therefore, ROHM has expanded its line-up of 100V power MOSFETs ideal for hot-swap circuits in AI servers to meet market demand. The new RS7P200BM adopts a compact DFN5060-8S (5060 size) package, enabling even higher density mounting compared to the AI server power MOSFET ‘RY7P250BM’ in the DFN8080-8S (8.0mm × 8.0mm size) package, which ROHM has released in May 2025.　　The new product achieves a low on-resistance (RDS(on)) of 4.0mΩ (conditions: VGS=10V, ID=50A, Ta=25°C) while maintaining wide SOA of 7.5A at a pulse width of 10ms and 25A at 1ms under operating conditions of VDS=48V. This balance of low on-resistance and wide SOA, typically a trade-off relationship, helps suppress heat generation during operation, thereby improving server power supply efficiency, reducing cooling load, and lowering electricity costs.　　Mass production of the new product began in September 2025 (sample price: $5.5/unit, excluding tax).　　ROHM will continue to expand its product lineup for 48V power supplies, which are increasingly adopted in applications such as AI servers. By providing highly efficient and reliable solutions, we will contribute to reducing power loss and cooling loads in data centers, as well as enhancing the high reliability and energy efficiency of server systems.　　Application Examples　　•48V system AI servers and data center power hot-swap circuits　　•48V system industrial power supplies (forklifts, power tools, robots, fan motors, etc.)　　•Battery-powered industrial equipment such as AGVs (Automated Guided Vehicles)　　•UPS, emergency power systems (battery backup units)　　EcoMOS™ Brand　　EcoMOS™ is ROHM's brand of silicon power MOSFETs designed for energy-efficient applications in the power device sector. Widely utilized in applications such as home appliances, industrial equipment, and automotive systems, EcoMOS™ provides a diverse lineup that enables product selection based on key parameters such as noise performance and switching characteristics to meet specific requirements.　　・EcoMOS™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　SOA(Safe Operating Area)　　The voltage and current range within which a device can operate safely without damage. Operation beyond this safe operating area may cause thermal runaway or damage; therefore, consideration of the SOA is essential, particularly in applications where inrush current or overcurrent may occur.　　Hot-swap circuit　　The complete circuitry supports the hot-swap function, which enables the removal or insertion of components while the device's power supply remains active. Comprising MOSFETs, protective elements, and connectors, it suppresses inrush currents occurring during component insertion and provides overcurrent protection, thereby ensuring the safe operation of the system and connected components.　　Inrush Current　　The high current exceeds the rated current value that flows momentarily when switching on electronic equipment. Controlling this prevents damage to devices and stabilizes the system by reducing the load on components within the power supply circuit.　　On-resistance(RDS(on))　　The resistance value between the drain and source terminals when the MOSFET is in operation (on). The lower the value, the less power loss occurs during operation.

ROHM’s Three-Phase Brushless DC Motor Gate Driver Achieving FET Heat Reduction while Suppressing EMI

　　ROHM has developed the “BD67871MWV-Z” three-phase brushless DC motor gate driver for medium voltage applications (12 to 48V systems). By incorporating ROHM’s proprietary gate drive technology TriC3™, it greatly reduces FET’s switching loss while maintaining low EMI – traditionally a trade-off in motor driver ICs.　　Motors account for approximately 60% of global electricity consumption, making control technology which affects energy efficiency, increasingly critical. In 12V to 48V motor drive applications, a simple configuration where an MCU controls three gate drivers has been the mainstream. However, in recent years, demands for high efficiency and precise control have grown, accelerating the adoption of solutions combining an MCU with an integrated three-phase motor driver. Further, a technical challenge in three-phase motor drivers has been the trade-off between “power consumption reduction” and “noise / EMI (electro-magnetic interference) reduction,”.　　BD67871MWV-Z features ROHM's proprietary Active Gate Drive technology “TriC3™”, which rapidly senses voltage information from the external power FETs and adjust gate drive current accordingly in real-time. This greatly reduces FETs’ switching loss (and hence heat generation) FET power consumption during switching while simultaneously suppressing ringing to achieve low EMI.　　Compared to ROHM's conventional constant-current drive products, TriC3™ gate drive has been demonstrated in actual motors that FET heat generation by approximately 35% while maintaining equivalent EMI levels. Furthermore, BD67871MWV-Z adopts UQFN28 package and pin layout which are commonly used in motor driver ICs for medium-voltage industrial equipment applications, contributing to reduced engineering effort required in circuit modifications and new designs.　　Mass production of the new product commenced in September 2025 (sample price: $5.5/unit, tax excluded).　　ROHM also offer general-purpose motor drivers (BD67870MWV-Z, BD67872MWV-Z) with the same package and pin configuration as the new product, designed for constant-voltage drive. From general-purpose types to the value-added types featuring the new TriC3™, we offer a comprehensive product lineup to supports a wide variety of applications and use cases. We are committed to contributing to improved motor efficiency, enhanced application functionality, and reduced power consumption.　　Application Examples　　•Industrial Equipment: Various motors such as electric drills/drivers and industrial fans　　•Consumer Appliances: Various motors used in vacuum cleaners, air purifiers, air conditioners, ventilation fans and E-bikes (electric-assist sports bicycles)　　TriC3™　　A multi-step constant current drive technology developed by ROHM. By controlling gate current in three steps, it achieves high-speed, high-efficiency operation while minimizing EMI by suppressing ringing.　　• TriC3™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　EMI (Electromagnetic Interference)　　EMI is used as an indicator of how much noise a product generates during operation, potentially causing malfunctions in surrounding ICs or systems. “Low EMI” means the product generates less noise.　　Ringing　　High-frequency oscillations or overshoot occurring during switching. This arises from the resonation between inductance and capacitance, including parasitic elements in the circuit. In the context of motor driving, ringing happens when the power MOSFETs are turned on and off.

ROHM Develops Breakthrough Schottky Barrier Diode Combining Low VF and IR for Advanced Image Sensor Protection

　　ROHM has developed an innovative Schottky barrier diode that overcomes the traditional VF / IR trade-off. This way, it delivers high reliability protection for a wide range of high-resolution image sensor applications, including ADAS cameras.　　Modern ADAS cameras and similar systems require higher pixel counts to meet the demand for greater precision. This has created a growing concern – the risk of damage caused by photovoltaic voltage generated under light exposure during power OFF. While low-VF SBDs are effective countermeasures, low IR is also essential during operation to prevent thermal runaway. However, simultaneously achieving both low VF and IR has been a longstanding technical challenge. ROHM has overcome this hurdle by fundamentally redesigning the device structure – successfully developing an SBD that combines low VF with low IR which is ideal for protection applications.　　The RBE01VYM6AFH represents a novel concept: leveraging the low-VF characteristics of rectification SBDs for protection purposes. By adopting a proprietary architecture, ROHM has achieved low IR that is typically difficult to realize with low VF designs. As a result, even under harsh environmental conditions, the device meets market requirements by delivering VF of less than 300mV (at IF=7.5mA even at Ta=-40°C), and an IR of less than 20mA (at VR=3V even at Ta=125°C.) These exceptional characteristics not only prevent circuit damage caused by high photovoltaic voltage generated when powered OFF, but also significantly reduce the risk of thermal runaway and malfunction during operation.　　The diode is housed in a compact flat-lead SOD-323HE package (2.5mm × 1.4mm / 0.098inch × 0.055inch) that offers both space efficiency and excellent mountability. This enables support for space-constrained applications such as automotive cameras, industrial equipment, and security systems. The RBE01VYM6AFH is also AEC-Q101 qualified, ensuring suitability as a protection device for next-generation automotive electronics requiring high reliability and long-term stability.　　Going forward, ROHM will focus on expanding its lineup with even smaller packages to address continuing miniaturization demands.　　Key Specifications　　Application Examples　　Image sensor-equipped sets such as ADAS cameras, smart intercoms, security cameras, and home IoT devices.　　Terminology　　Photovoltaic Voltage　　A term commonly used with optical sensors, referring to the voltage produced when exposed to light. In general, the stronger the light intensity or higher the pixel count the greater voltage generated.

ROHM has Developed New Smart Switches Optimized for Zonal Controllers

　　ROHM has developed six new high-side Smart Switches (Intelligent Power Devices, short: IPDs) BV1HBxxxEFJ series (BV1HB008EFJ-C, BV1HB012EFJ-C, BV1HB020EFJ-C, BV1HB040EFJ-C, BV1HB090EFJ-C, BV1HB180EFJ-C) with highly accurate current sensing capability and ON resistances from 9 mΩ to 180 mΩ. They are ideal for protecting loads and subsystems from abnormalities such as overcurrent, overvoltage, and overtemperature, ensuring reliable operation and safeguarding sensitive components in automotive lighting, body control such as, door locks and power windows. Extensive diagnostic capabilities, e.g., open load and reverse battery detection, further enhances safety and reliability.　　Vehicle electronic control systems are becoming increasingly sophisticated with the advancement of autonomous driving and electric vehicles (EVs). This evolution has heightened the importance of electronic protection from a functional safety standpoint, driving the shift toward Zonal Controllers architecture that manages vehicle functions in designated zones. As a result, the use of smart switches for electronic load protection and control is rapidly growing.　　Zonal controllers must each manage a large number of loads, but conventional smart switches often lack the drive capability required for high-capacitance loads. ROHM’s new smart switches address this challenge, delivering key performance attributes such as low ON resistance and high inductive energy clamp while significantly improving capacitive load drive capability. By commercializing high-performance smart switches tailored to zonal controllers’ requirements, ROHM is contributing to automotive electrification and the elimination of mechanical fuses.　　The new products feature exceptional high-capacitance load driving capability, maximizing performance at the critical interface between Zonal Controllers and output loads (including various ECUs). Leveraging proprietary cutting-edge process technology makes it possible to achieve both low ON resistance and high inductive energy clamp – two characteristics typically involve a trade-off. The result is a well-balanced integration of three key performance metrics: drive capability, ON resistance, and energy tolerance. This enhances system design safety, efficiency, and reliability. The devices also incorporate a best-in-class* high-precision current sensing function (±5%) that provides effective protection for harnesses connected to output loads. At the same time, the compact, high heat dissipation HTSOP-J8 package ensures excellent design versatility.　　Going forward, ROHM remains committed to improving safety, security, and energy efficiency in the automotive field by continuing to develop high reliability, high performance devices.　　*ROHM study on high-side Smart Switches - September 30th, 2025　　Application Examples　　Body applications, powertrain/inverter systems, other switch-related circuits　　Terminology　　Zonal Controllers　　An emerging design concept in automotive electronic architecture, zonal controllers represent a shift away from the conventional approach of assigning dedicated ECUs for each function, such as lighting, door locks, and power windows. Instead, the vehicle is divided into zones, with a zonal controller manages multiple functions in its zone.　　Intelligent Power Devices (IPD) / Smart Switches　　Smart power switches are semiconductor devices that electronically control the delivery of power by turning it on and off, while also providing integrated protection and diagnostic features such as overcurrent, overvoltage, thermal shutdown, current sensing, and open load detection to enhance system reliability and safety.　　Capacitive Load Driving Capability　　A technical term referring to the ability of an electronic circuit or semiconductor device to operate reliably when driving capacitive loads. It is especially important in circuit configurations involving zone ECUs and their output stages (including individual ECUs) where large electrolytic capacitors are commonly used. If this capability is inefficient, inrush current cannot be adequately suppressed, leading to overheating that can result in malfunctions or reduced operational lifespan.

ROHM Launches 2-in-1 SiC Molded Module “DOT-247”

　　ROHM has developed the "DOT-247," a 2-in-1 SiC molded module (SCZ40xxDTx, SCZ40xxKTx), ideal for industrial applications such as PV inverters, UPS systems, and semiconductor relays. The module retains the versatility of the widely adopted "TO-247" package while achieving high design flexibility and power density.　　The DOT-247 features a combined structure consisting of two TO-247 packages. This design enables the use of large chips, which were structurally difficult to accommodate in the TO-247 package, and achieves low on-resistance through an unique internal structure. Additionally, through optimized package structure, thermal resistance has been reduced by approximately 15% and inductance by approximately 50% compared to the TO-247. This enables a power density 2.3 times higher than the TO-247 in a half-bridge configuration –achieving the same power conversion circuit in approximately half the volume.　　The new products featuring the DOT-247 package are available in two topologies: half-bridge and common-source. Currently, two-level inverters are the mainstream in PV inverters, but there is growing demand for multi-level circuits such as three-level NPC, three-level T-NPC, and five-level ANPC to meet the need for higher voltages. In the switching sections of these circuits, topologies such as half-bridge and common-source are mixed –making custom products necessary in many cases when using conventional SiC modules.　　To address this challenge, ROHM has developed each of these two topologies—the smallest building blocks of multi-level circuits—into a 2-in-1 module. This enables flexibility to support various configurations such as NPC circuits and DC-DC converters, while significantly reducing the number of components and mounting area, and achieving circuit miniaturization compared to discrete components.　　Evaluation boards will also be made available progressively to facilitate evaluation during application design. For more information, please contact a sales representative or visit the contact page on ROHM’s website.　　Product Lineup　　☆:Under Development　　AEC-Q101 is an automotive electronics reliability standard established by the Automotive Electronics Council (AEC).　　The Q101 standard is specifically focused on discrete semiconductor components.　　Application Examples　　PV inverters, semiconductor relays, UPS (uninterruptible power supply), ePTO, and boost converters for FCVs (fuel cell vehicles).　　AI servers (eFuse), EV charging stations, etc.　　Sales Information　　Pricing: $140/unit (samples, excluding tax)　　Availability: ROHM construct mass production (September 2025)　　Products compliant with the automotive reliability standard AEC-Q101 are scheduled to begin sample shipments in October 2025.　　Comprehensive Support　　ROHM is committed to providing application-level support, including the use of in-house motor testing equipment. A variety of supporting materials are also offered, such as simulations and thermal designs that enable quick evaluation and adoption of DOT-247 products. An evaluation kit for double-pulse testing is already available, allowing immediate testing, while an evaluation kit for 3-phase inverters is currently under preparation, with reference designs scheduled to be released from November 2025.　　• About the DOT-247 design models　　SPICE models: Available on the product web pages for each part number　　LTspice® models: Scheduled to be available for three-level NPC from October 2025 on the web pagesLTspice® is a registered trademark of Analog Devices, Inc.When using third-party trademarks, please adhere to the usage guidelines specified by the rights holder.　　For details, please contact a sales representative or visit the contact page on ROHM’s website.　　EcoSiC™ Brand　　EcoSiC™ is a brand of devices that utilize silicon carbide (SiC), which is attracting attention in the power device field for performance that surpasses silicon (Si).

At the same time, we have established an integrated production system throughout the manufacturing process, solidifying our position as a leading SiC supplier.• EcoSiC™ is a trademark or registered trademark of ROHM Co., Ltd.　　Terminology　　Half-bridge/ Common-source　　A basic configuration of a power conversion circuit consisting of two MOSFETs. In a half-bridge configuration, the MOSFETs are connected in series, one above the other, and the output is taken from the connection point. By switching the upper and lower MOSFETs alternately, the output voltage can be switched between positive and negative, making this configuration widely used as the basic structure for high-efficiency power conversion in inverters and motor drive circuits.　　Common Source is a configuration where the source terminals of the two MOSFETs are connected, and the output is taken from each drain. By grouping the source terminals, the gate drive circuit can be simplified, making it suitable for applications such as multilevel inverters.　　Types of NPC-type multi-level circuits　　NPC (Neutral Point Clamped) is a multi-level circuit configuration that divides the output voltage into three levels (+, 0, and -) to reduce voltage stress on the switching devices. The "0V" state is created by the neutral point, which is the contact point located between the positive and negative voltages.　　T-NPC (T-type NPC) replaces the diode used to stabilize the neutral point with switching devices such as MOSFETs, enabling more efficient operation. ANPC (Active NPC) actively controls the potential of the neutral point itself using a switch, achieving smoother output waveforms and high-precision power conversion. T-NPC and ANPC are suitable for applications requiring higher output and efficiency.　　ePTO (electric Power Take-Off)　　A system that uses the power from an electric vehicle's motor or battery to drive external work machinery or equipment (such as hydraulic pumps or compressors). This is an electrified version of the PTO (Power Take-Off) used in conventional engine vehicles, and its adoption is advancing in environmentally friendly commercial vehicles and work vehicles.

ROHM has Developed Ultra-Compact CMOS Op Amp: Delivering Industry-Leading* Ultra-Low Circuit Current

　　ROHM’s ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry’s lowest operating circuit current. This IC is optimized to be applied as a measurement sensing amplifier in size-constrained applications such as handheld measurement instruments, wearable devices, and indoor motion detectors.　　As the demand continues to grow for more sophisticated control in battery-driven devices, the importance of sensors that detect parameters such as temperature, humidity, vibration, pressure, and flow rate – along with the op amps used to amplify these sensor signals – continues to rise. At the same time, greater miniaturization and energy savings in applications is a necessary step to realizing a sustainable society –placing similar demands on individual devices as well.　　In response to these evolving market needs, ROHM has advanced its process, packaging, and proprietary Nano Energy™ circuit technologies to develop an op amp that addresses three key requirements: lower power consumption, higher accuracy, and compact size. The newly developed TLR1901GXZ achieves an ultra-compact footprint of less than 1mm2 by adopting a WLCSP (Wafer Level Chip Scale Package) with a fine ball pitch of 0.35mm while delivering an industry-leading low operating current of 160nA (typ.). This not only contributes to high-density mounting in space-constrained applications, but also to a significantly extended battery life.　　Moreover, the TLR1901GXZ features an exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps. This represents an approximate 45% reduction compared to typical products on the market. A maximum input offset voltage temperature drift of 7uV/°C ensures high accuracy operation over the operating temperature range.　　Design flexibility can be further enhanced by pairing the op amp with ROHM’s ultra-compact general-purpose resistors, such as the MCR004 (0402 metric / 01005 inch) and MCR006 (0603 metric / 0201 inch), for applications like gain adjustment.

ROHM’s SiC MOSFETs Adopted in Schaeffler’s Inverter Brick, Now in Mass Production

　　ROHM and Schaeffler, a leading German automotive supplier, have started mass production of a new high-voltage inverter brick equipped with ROHM’s SiC (silicon carbide) MOSFET bare chips as part of their strategic partnership. The inverter brick is intended for a major Chinese car manufacturer.High voltage inverter brickSiC MOS Wafer　　The Schaeffler inverter subassembly is the essential power device building block (brick) to control the electric drive via logic signals. This is where the high-frequency current pulses are produced that set the vehicle’s electric motor in motion. The performance characteristics of the inverter brick now being produced are impressive: Schaeffler increased the output of the brick by increasing the maximum possible battery voltage to much more than the usual 800 V – and with RMS currents of up to 650 A, which turn the sub-module into a compact power pack.　　“Through our strategic approach of incorporating scalability and modularity into our e-mobility solutions – from individual components to a highly integrated electric axle – we developed the readily integrated inverter brick. Based on our generic platform development, it took us just one year to bring this optimal product for the popular X-in-1 architectures to volume production readiness,” says Thomas Stierle, CEO of the E-Mobility Division at Schaeffler.　　Modularity and scalability as the key to easy integration　　As a core component of an inverter, a brick has to meet strict requirements. The characteristics of the sub-module are indicative of the factors behind the current sales success and start of volume production: ROHM’s silicon carbide (SiC) power semiconductors enable the frame-mounted sub-module with high power density to be compact, efficient, and readily integrated into various inverters through its modular and scalable design. The sub-module incorporates the power module for pulse width modulation (PWM) of the current pulses, the DC link capacitor, a DC link and a cooler. Moreover, the brick has a DC boost function, thanks to which a vehicle with 800 V architecture can also be charged at a 400 V charging station at a charging speed of 800 V.　　“We are glad about the launch of volume production for Schaeffler’s inverter brick with our 4th generation SiC MOSFET,” says Dr. Kazuhide Ino, Member of the Board and Managing Executive Officer at ROHM. “With our SiC technology we are making a substantial contribution to increasing the efficiency and performance of electric cars. Working with Schaeffler as our partner, we are thus fostering innovation and sustainability in the automotive industry,” Dr. Ino adds.　　The strategic partnership of Schaeffler (originally initiated under Vitesco Technologies) with ROHM has existed since 2020 and serves to secure capacity for energy-efficient SiC power semiconductors.Thomas Stierle, CEO E-Mobility Division at Schaeffler (left) and Dr. Kazuhide Ino, Member of the Board and Managing Executive Officer at ROHM　　About Schaeffler Group　　The Schaeffler Group has been driving forward groundbreaking inventions and developments in the field of motion technology for more than 75 years.
