在开关电源中，比较常用的防雷保护器件产品有两种，分别是GDT陶瓷气体放电管及MOV压敏电阻。本文优恩半导体将重点介绍GDT放电管在开关电源防雷保护中的应用。

整个防雷思路在于MOV压敏电阻和GDT放电管单相并联在防雷击瞬态浪涌电路，并应用于被保护产品的开关电源上，这时整个PCB就有防雷和开关电源电路。

防雷电路可采用压敏电阻+GDT放电管组合成复核对称电路，提供差模和共模保护，使其与开关电源的电路组合成防雷的电源电路，与MOV压敏电阻并联使用的这种方式，既可以延长其寿命，还能在MOV短路失效之后，达到与开关电源电路的分离，从而避免了火灾的产生，在整个开关电源防雷保护中，一般GDT放电管是用作电路的一级保护，在后端串联MOV压敏电阻来泄放掉残余电压。

防雷防护是开关电源产品极为重要的一环，由于寄生电容的存在，雷电在过电压击穿常压下绝缘的空气或设备，会形成强大的雷电流，势必会造成设备的不同程度损坏，因此，在开关电源防雷保护中，GDT陶瓷气体放电管发挥着很大作用。

【经验】GDT放电管与MOV压敏电阻串联使用时是否导通在前？

GDT放电管与压敏电阻两个器件串联时，通常小容量的分压较高，大容量的分压较小，MOV压敏电阻的寄生电容是陶瓷气体放电管的百倍，因此绝大部分的电压会给到放电管，放电管导通之后，再施加到压敏电阻上，此时压敏电阻就会导通。

DC24V电源端口浪涌保护

DC24V电源端口浪涌保护DC24V电源是一种为设备提供稳定、可靠的直流电压输出的电源，其广泛应用于工业自动化控制系统。此方案设计为多级保护的方式，初级采用通流能力较强的陶瓷气体放电管和压敏电阻组合来承受泻放大的浪涌电流，中间使用电感做退耦，次级选用响应电压精准、稳定且快速的TVS管做保护，能有效抑制各类浪涌过电压，使后端的DC芯片及电路得到全面的保护。
