Pxxx0S3H SIDACtor®保护晶闸管系列

  Pxxx0S3H系列专为苛刻环境中的交流和直流电源线而设计, 可为工业电源、电池充电系统、太阳能逆变器、UPS/AC配电系统和ICT设备等应用提供出色的浪涌抗扰度。Pxxx0S3H具备高电流处理能力和紧凑的外形尺寸,可帮助工程师在满足IEC 61000-4-5 4级要求的同时减小器件的整体尺寸。

  “设计工程师正面临着越来越大的压力,需要在不牺牲安全性的前提下将更多功能集成到更小的封装中。”Littelfuse保护半导体业务产品营销管理总监Ben Huang表示, “Pxxx0S3H系列凭借紧凑的封装、抗浪涌能力和合规性优势,精准满足了这一需求—远胜于性能会随时间衰减的传统MOV和GDT解决方案。”

  主要差异和优势

  在紧凑结构中提供高浪涌保护能力:首款采用DO-214AB封装的2kA(8/20μs)浪涌额定值保护晶闸管,尺寸远小于传统TO-262解决方案。

  长期可靠性:采用基于半导体的设计,与传统的基于GDT或MOV的器件不同,可承受反复的高能量浪涌事件而不会降低性能。

  合规性:有助于系统满足IEC-61000-4-5 4级浪涌抗扰度标准。

  顺应微型化趋势:紧凑的尺寸(6.22mm×7.11mm×2.62mm),支持密集型工业、汽车和太阳能系统设计。

  灵活部署:可以单独使用,也可以与MOV结合使用,以实现量身定制的保护架构。

  目标市场和应用

  工业和工厂自动化电源

  电池管理和电动汽车壁式充电系统

  太阳能DC/AC逆变器保护

  不间断电源设备(UPS)和大电流交流配电

  恶劣环境中的ICT基础设施储能系统和物联网连接功率器件

  Pxxx0S3H系列使工程师得以替换掉笨重且性能容易退化的保护组件,设计出更小、更可靠、更持久的系统。
