必易微800V耐压高可靠性SSR反激开关管KPE3638X ，满足白电或者工业电源客户要求

时间： 2024-08-28 来源：必易微公众号

技术问答

为满足白电或者工业电源客户更高的品质要求，必易微2024年将推出一整套800V耐压合封开关管产品，包括非隔离Buck、非隔离反激、PSR反激和SSR反激。希望能为行业再添高可靠性辅助电源解决方案。

KPE3638X系列产品从成熟物料KP3637X升级而来，在保留成熟控制核心的同时，将低压引脚的耐压极限提高（规格书标称15V、实测20V以上），有助于抵抗产线上的异常电压冲击，从而降低不良率。

KPE3638X典型应用框图

引脚极限耐压

1.低压引脚产线损伤机理

大家在使用反激SSR的经历中，多少都遇到过芯片VDD引脚或者FB引脚莫名损伤失效的情况。从理论上讲，FB引脚的工作电压不会超过5V，而且引脚上通常放置有贴片电容，怎么会过压损坏呢？经过调查，我们找到了低压引脚损伤的一种机理。以冰箱或者空调为例，压缩机部件只能做到基本绝缘，所以必须接地（PE）；变频控制板往往也经过Y 容接地或者直接接地。在浪涌电压的作用下，压缩机绕组有可能对控制板放电；由于放电的路径复杂，高压毛刺有可能直接串入IC的低压引脚，从而导致低压引脚损伤。

应对此类失效，最简单直接的办法，就是把芯片低压引脚的耐压极限提升。

2.极限耐压对照表

与友商产品相比，KPE3638X的VDD、FB、BR、CS引脚耐压极限均大幅提升。实际测试，VDD引脚的击穿电压为41V；FB、BR和CS引脚的击穿电压为25V。

丰富的保护功能

KPE3638X还提供完善的保护功能，包括过载保护OLP、VDD过压保护VDD OVP、线电压过压保护Line OVP、线电压欠压保护Line BOP、过温保护OTP、异常过流保护AOCP和CS/GND引脚开路保护等。

产品选型表
KPE3638X提供三种合封MOSFET规格和两种封装形式。其中，SMP-7可以理解为DIP-7折脚，对生产制程更加友好。

KPE3638X集合成熟的技术IP、先进的0.18μm晶圆工艺制程和可靠的800V功率器件，主打一个靠谱！
