ROHM Introduces a New MOSFET for AI Servers with Industry-Leading* SOA Performance and Low ON-Resistance

　　ROHM has released of a 100V power MOSFET - RY7P250BM - optimized for hot-swap circuits in 48V power systems used in AI servers and industrial power supplies requiring battery protection to the market.　　As AI technology rapidly advances, data centers are facing unprecedented processing demands and server power consumption continues to increase annually. In particular, the growing use of generative AI and high-performance GPUs has created a need to simultaneously improve power efficiency while supporting higher currents. To address these challenges, the industry is shifting from 12V systems to more efficient 48V power architectures. Furthermore, in hot-swap circuits used to safely replace modules while servers remain powered on, MOSFETs are required that offer both wide SOA (Safe Operating Area) and low ON-resistance to protect against inrush current and overloads.　　The RY7P250BM delivers these critical characteristics in a compact 8080-size package, helping to reduce power loss and cooling requirements in data centers while improving overall server reliability and energy efficiency. As the demand for 8080-size MOSFETs grows, this new product provides a drop-in replacement for existing designs. Notably, the RY7P250BM achieves wide SOA (VDS=48V, Pw=1ms/10ms) ideal for hot-swap operation. Power loss and heat generation are also minimized with an industry-leading low ON-resistance of 1.86mΩ (VGS=10V, ID=50A, Tj=25°C), approximately 18% lower than the typical 2.28mΩ of existing wide SOA 100V MOSFETs in the same size.　　Wide SOA tolerance is essential in hot-swap circuits, especially those in AI servers that experience large inrush currents. The RY7P250BM meets this demand, achieving 16A at 10ms and 50A at 1ms, enabling support for high-load conditions conventional MOSFETs struggle to handle.　　ROHM’s new product has also been certified as a recommended component by leading global cloud platform provider, where it is expected to gain widespread adoption in next-generation AI servers. Especially in server applications where reliability and energy efficiency are mission-critical, the combination of wide SOA and low RDS(on) has been highly evaluated for cloud infrastructure.　　Going forward, ROHM will continue to expand its lineup of 48V-compatible power solutions for servers and industrial equipment, contributing to the development of sustainable ICT infrastructure and greater energy savings through high-efficiency, high-reliability products.　　Application Examples　　• 48V AI server systems and power supply hot-swap circuits in data centers　　• 48V industrial equipment power systems (i.e. forklifts, power tools, robots, fan motors)　　• Battery-powered industrial equipment such as AGVs (Automated Guided Vehicles)　　• UPS and emergency power systems (battery backup units)　　Online Sales InformationSales Launch Date: May 2025　　Pricing: $5.50/unit (samples, excluding tax)　　Online Distributors: DigiKey™, Mouser™ and Farnell™　　The products will be offered at other online distributors as they become available.　　Applicable Part No: RY7P250BM　　EcoMOS™ BrandEcoMOS™ is ROHM's brand of silicon 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.　　TerminologyHot-Swap Circuit　　A circuit that enables components to be inserted or removed while the system remains powered on.　　It typically consists of MOSFETs, protection elements, and connectors, and is responsible for suppressing inrush current and protecting against overcurrent conditions, ensuring stable operation of the system and connected components.　　Power MOSFET　　A MOSFET designed for power conversion and switching applications. N-channel MOSFETs are the dominant type, turning on when a positive voltage is applied to the gate relative to the source. They offer lower ON-resistance and higher efficiency than P-channel variants.

ROHM Develops Class-Leading* Low ON-Resistance, High-Power MOSFETs for High-Performance Enterprise and AI Servers

　　ROHM has developed N-channel power MOSFETs featuring industry-leading* low ON-resistance and wide SOA capability. They are designed for power supplies inside high-performance enterprise and AI servers.　　The advancement of high-level data processing technologies and the acceleration of digital transformation have increased the demand for data center servers. At the same time, the number of servers equipped with advanced computing capabilities for AI processing is on the rise and is expected to continue to grow. These servers operate 24 hours a day, 7 days a week – ensuring continuous operation. As a result, conduction losses caused by the ON-resistance of multiple MOSFETs in the power block have a significant impact on system performance and energy efficiency. This becomes particularly evident in AC-DC conversion circuits, where conduction losses make up a substantial portion of total power loss – driving the need for low ON-resistance MOSFETs.　　Additionally, servers equipped with a standard hot-swap function, which allow for the replacement and maintenance of internal boards and storage devices while powered ON, experience a high inrush current during component exchanges. Therefore, to protect server components and MOSFETs from damage, a wide Safe Operating Area (SOA) tolerance is essential.　　To address these challenges, ROHM has developed its new DFN5060-8S package that supports the packaging of a larger die compared to conventional designs, resulting in a lineup of power MOSFETs that achieve industry-leading* low ON-resistance along with wide SOA capability. These new products significantly contribute to improving efficiency and enhancing reliability in server power circuits.　　The new lineup includes three products. The RS7E200BG (30V) is optimized for both secondary-side AC-DC conversion circuits and hot-swap controller (HSC) circuits in 12V power supplies used in high-performance enterprise servers. The RS7N200BH (80V) and RS7N160BH (80V) are ideal for secondary AC-DC conversion circuits in 48V AI server power supplies.　　All three models feature the newly developed DFN5060-8S package (5.0mm × 6.0mm). The package increases the internal die size area by approximately 65% compared to the conventional HSOP8 package (5.0mm × 6.0mm). As a result, the RS7E200BG (30V) and RS7N200BH (80V) achieve ON-resistances of 0.53mΩ and 1.7mΩ (at VGS = 10V), respectively – both of which rank among the best in the industry in the 5.0mm × 6.0mm class, significantly contributing to higher efficiency in server power circuits.　　Moreover, ROHM has optimized the internal clip design to enhance heat dissipation, further improving SOA tolerance, which contributes to ensuring application reliability. Notably, the RS7E200BG (30V) achieves an SOA tolerance of over 70A at a pulse width of 1ms and VDS = 12V, which is twice that of the conventional HSOP8 package MOSFETs under the same conditions, ensuring industry-leading SOA performance in a 5.0mm × 6.0mm footprint.　　Going forward, ROHM plans to gradually begin mass production of power MOSFETs compatible with hot-swap controller circuits for AI servers in 2025, continuing to expand its lineup that contributes to greater efficiency and reliability across a wide range of applications.　　Product Lineup　　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.　　Application Examples　　・AC-DC conversion and HSC circuits for 12V high-performance enterprise server power supplies　　・AC-DC conversion circuits for 48V AI server power supplies　　・48V industrial equipment power supplies (i.e. fan motors)　　Terminology　　Low ON-Resistance (RDS(on))　　The resistance value between the Drain and Source of a MOSFET during operation. A smaller RDS(on) results in lower power loss during operation.　　SOA (Safe Operating Area) Tolerance　　The range of voltage and current within which a device can operate safely without damage. Exceeding this range can lead to thermal runaway or device failure, making SOA tolerance a critical factor, especially in applications prone to inrush current or overcurrent.　　Power MOSFET　　A type of MOSFET used for power conversion and switching applications. N-channel MOSFETs are the mainstream choice, as they become conductive when a positive voltage is applied to the gate relative to the source, offering lower ON-resistance and higher efficiency than P-channel variants. Due to their low loss and high-speed switching capabilities, power MOSFETs are widely used in power circuits, motor drive circuits, and inverters.　　Hot-Swap Controller (HSC)　　A specialized integrated circuit (IC) that enables hot-swap functionality, allowing components to be inserted or removed while the power supply system remains active. It plays a crucial role in managing inrush current that occurs during component insertion, protecting both the system and connected components from damage.　　Inrush Current　　A sudden surge of current that momentarily exceeds the rated value when an electronic device is powered ON. Proper control of this current reduces stress on power circuit components, helping to prevent device failure and stabilize the system.

ROHM’s Compact SOT-223-3 600V MOSFETs Contribute to Smaller, Lower Profile Designs for Lighting Power Supplies, Pumps, and Motors

　　ROHM has added a lineup of compact 600V Super Junction MOSFETs - the R6004END4 / R6003KND4 / R6006KND4 / R6002JND4 / R6003JND4. These devices are ideal for small lighting power supplies, pumps, and motors.　　In recent years, power supplies for lighting and motors for pumps are required to be smaller as devices become more sophisticated - spurring the demand for compact MOSFETs that are essential for switching operation.　　Generally, however, it has been difficult to reduce the size of Super Junction MOSFETs while maintaining an optimal balance between high breakdown voltage and low ON resistance. In response, after reviewing the shape of the mounted chip, ROHM was able to develop 5 models in the SOT-223-3 package (6.50mm × 7.00mm × 1.66mm) - providing a smaller, lower profile form factor without compromising the performance of conventional products.　　Compared to the conventional TO-252 package (6.60mm × 10.00mm × 2.30mm), ROHM’s new products reduce area and thickness by 31% and 27% - contributing to smaller, lower profile applications. At the same time, the same land pattern (footprint) as the TO-252 package can be used, enabling mounting on existing circuit boards without modification.　　Offering distinctive features, three of the models optimized for compact power supplies. The R6004END4, characterized by low noise, is suitable for applications where noise is a concern, while the R6003KND4 and R6006KND4, capable of high-speed switching, are ideal for sets requiring low loss, high efficiency operation. The R6002JND4 and R6003JND4 utilize proprietary PrestoMOS technology to achieve significantly lower switching losses by speeding up reverse recovery time (trr), making them well-suited for motors-equipped devices.　　Supporting materials such as application notes, technical documents, and SPICE simulation models for each product are available on ROHM’s website free of charge to enable quick market introduction.　　Going forward, ROHM will continue to expand its Super Junction MOSFET lineup in different packages and even lower ON resistances that contribute to solving social issues such as environmental protection by reducing power consumption in variety devices.　　Product Lineup　　For compact power supplies　　Application Examples        • R6004END4 / R6003KND4 / R6006KND4: Lighting, Air conditioners, Refrigerators, etc.　　• R6002JND4 / R6003JND4: Motors for pumps, fans, copiers, etc.　　Online Sales InformationSales Launch Date: December 2023　　Pricing: $3.0/unit (samples, excluding tax)　　Online Distributors: DigiKey, Mouser, and Farnell　　The products will be offered at other online distributors as they become available.　　Online Distributors　　For More Information about ROHM’s Super Junction MOSFETVarious resources are available on ROHM's website, including application notes on the SOT-223-3 package and other documents essential for circuit design.　　https://www.rohm.com/support/super-junction-mosfet　　PrestoMOS“Presto” is an Italian musical term meaning “very fast.”　　PrestoMOS is ROHM’s original power MOSFET that maintains the high withstand voltage and low ON resistance of Super Junction MOSFETs while speeding up the reverse recovery time of the built-in diode.

ROHM’s New 5-Model Lineup of Low ON Resistance 100V Dual MOSFETs

　　ROHM has developed dual MOSFETs that integrate two 100V chips in a single package - ideal for fan motor drive applied in communication base stations and industrial equipment. New five-models have been added as part of the HP8KEx/HT8KEx (Nch+Nch) and HP8MEx (Nch+Pch) series.　　Recent years have seen a transition to higher voltages from conventional 12V/24V to 48V systems in communication base stations and industrial equipment, - intending to achieve higher efficiency by reducing current values. In these situations, switching MOSFETs are required a withstand voltage of 100V to account for voltage fluctuations, as 48V power supplies are also used in the fan motors for cooling these applications. However, increasing the breakdown voltage raises ON resistance (RDS(on)) (which is in a trade-off relationship), leading to decreased efficiency, making it difficult to achieve both lower RDS(on) and higher breakdown voltage. Moreover, unlike multiple individual drive MOSFETs normally applied in fan motors -　dual MOSFETs that integrate two chips in one package are increasingly being adopted to save space.　　In response, ROHM developed two new series - the HP8KEx/HT8KEx (Nch+Nch) and the HP8MEx (Nch+Pch) - that combine Nch and Pch MOSFET chips using the latest processes. Both series achieve the industry’s lowest RDS(on) by adopting new backside heat dissipation packages with excellent heat dissipation characteristics. As a result, RDS(on) is reduced by up to 56% compared with standard dual MOSFETs (19.6mΩ for the HSOP8 and 57.0mΩ for the HSMT8 Nch+Nch), contributing to significantly lower set power consumption. At the same time, combining two chips in a single package provides greater space savings by reducing area considerably. For example, replacing two single-chip TO-252 MOSFETs with one HSOP8 decreases footprint by 77%.　　Next, ROHM will continue to expand its dual MOSFET lineup to withstand voltages ideal for industrial equipment while also developing low-noise variants. This is expected to contribute to solving social issues such as environmental protection by saving space and reducing power consumption in various applications.　　Application Examples        - Fan motors for communication base stations　　- Fan motors for factory automation, and other industrial equipment　　- Fan motors for data center servers, etc.　　Combination with a pre-driver IC to achieve the optimal motor drive solutionCombining these products with ROHM’s market-proven pre-driver ICs for single-/3-phase brushless motors make it possible to consider even smaller motors featuring lower consumption and quieter drive. By providing total support for peripheral circuit design that marries the dual-MOSFET series with pre-driver ICs, ROHM can offer the best motor drive solutions for customer needs.　　Solution examples with 100V Dual MOSFETs　　- HT8KE5 (Nch+Nch Dual MOSFET) + BM64070MUV (3-Phase Brushless Motor Pre-Driver IC)　　- HT8KE6 (Nch+Nch Dual MOSFET) + BM64300MUV (3-Phase Brushless Motor Pre-Driver IC) and more

ROHM’s New 600V Super Junction MOSFETs Combine Class-Leading Noise Characteristics with the Industry’s Fastest* Reverse Recovery Time

　　ROHM has added three new models, the R60xxRNx series, to its PrestoMOS™ lineup of 600V Super Junction MOSFETs. These devices are optimized for driving small motors in refrigerators, ventilation fans, and other applications where noise suppression is important.　　Greater energy efficiency in equipment is required in recent years in response to the tightening of the global power supply, with motor drives accounting for up to 50% of the world’s total power demand. For this reason, high efficiency MOSFETs are increasingly being used in inverter circuits that convert power to drive motors. At the same time, however, countermeasures against noise generated from MOSFET operation typically involve adding components and/or changing circuit patterns, so there is a need to reduce both man-hours and costs. But reducing power loss and noise are generally in a trade-off relationship, making it difficult to achieve both.　　To meet these needs, in 2012, ROHM began mass production of the PrestoMOS™ lineup of Super Junction MOSFETs featuring the industry's fastest reverse recovery time(trr) characteristics, which has received high marks for achieving lower power consumption. The lineup now includes three new models that provide best-in-class noise characteristics while maintaining the fast trr through an optimized structure.　　The new R60xxRNx series maintains the high-speed trr characteristics of PrestoMOS™ while minimizing noise. An industry-best trr of 40ns is achieved by improving conventional lifetime control technology, reducing switching losses by approx. 30% over general products that translates to lower application power loss. At the same time, the newly developed Super Junction structure reduces noise characteristics (which are inversely related to faster trr) by about 15dB compared to standard products (under ROHM measurement conditions at 40MHz). Delivering industry-leading characteristics reduces the number of man-hours and parts required for noise countermeasures.　　Going forward, ROHM will continue to expand its high voltage MOSFET lineup in different packages and even lower ON resistances that contribute to environmental protection by reducing power consumption in a variety of applications.　　ROHM’s New 600V Super Junction MOSFETs Combine Class-Leading　　Noise Characteristics with the Industry’s Fastest* Reverse Recovery Time　　Contributes to lower power loss along with fewer man-hours and external parts required for noise suppression in devices equipped with small motors*ROHM July 13th, 2023 study　　Product LineupOnline Sales InformationVideoFeatured Products　　July 13th, 2023　　ROHM has added three new models, the R60xxRNx series, to its PrestoMOS™ lineup of 600V Super Junction MOSFETs.

Reducing switching losses make it ideal for a wider range of applications with inverter circuits, such as air conditioners and refrigerators.　　*PrestoMOS™ is a trademark or registered trademark of ROHM Co., Ltd.　　Application Examples◇ Refrigerators◇ Ventilation fans◇ Fan motorsAlso suitable for a variety of devices equipped with small motors.　　Online Sales InformationSales Launch Date: March 2023　　Online Distributors: DigiKey, Mouser, and Farnell　　Pricing: $3.5/unit (samples, excluding tax)　　Products and evaluation boards will be offered at online distributors as they become available.　　TerminologySuper Junction MOSFET (Metal Oxide Semiconductor Field Effect Transistor)　　A type of transistor, MOSFETs can be divided by device structure into DMOSFET (Double-diffused MOSFET), planar, and super junction topologies. Super Junction MOSFETs deliver superior breakdown voltage and output current than both DMOSFETs and planar types, while also featuring lower loss when handling large power.　　trr (Reverse Recovery Time)　　The time it takes for the built-in diode to switch from the ON state to completely OFF. The lower this value is, the smaller the loss during switching.　　Lifetime Control　　The time it takes for carriers (holes or electrons) that have moved when voltage is applied to the semiconductor to recombine when the voltage is stopped is called the lifetime, and the technology that makes recombination easier by intentionally creating defects in the semiconductor crystal structure is called lifetime control.
