【技术】解析GDT陶瓷气体放电管与元器件间的连接方式
元器件间的连接方式通常有三种方式:串联电路,并联电路与串并联电路。
图1 实物图
陶瓷气体放电管作为雷击浪涌防护器件,其特点为体积小,电流容量大,极间电容小,但在电源防雷应用中,将会面临持续电流无法关闭的问题,因此通常要与其他器件一起搭配使用,如MOV压敏电阻,压敏电阻的电流容量大,成本相对较低,但在电源防雷应用中,会面临击穿、短路导致火灾的问题,所以两者都不合适单用。
那么,在实际过程中,它们之间是如何连接的呢?由于GDT陶瓷气体放电管与MOV压敏电阻的特性,通常都会选择串联使用,陶瓷气体放电管起到开关的作用,在没有瞬态过电压的情况下,放电管将压敏电阻与系统隔开,使压敏电阻几乎没有漏电流,有效缓解了压敏电阻的性能退化。
在瞬态过电压装置中,由于压敏电阻的参考电压Uima选择得较低,只要能够使GDT放电管快速放电并导通,串联支路可以给出比单个压敏电阻更低的钳位电压,从而达到浪涌雷击防护作用。

关于陶瓷气体放电管与SPG玻璃放电管相信大家并不陌生,那么他们有哪些共同点呢?本文优恩半导体将为您进行介绍。相比于其他的一些浪涌保护器件来说,放电管通常都是用作一级保护,用来泄放浪涌电流以及钳制浪涌电压。
解析TSS半导体放电管基本概念以及特征表现
本文中优恩半导体将为大家简要解析TSS半导体放电管基本概念以及特征表现。半导体放电管,简称TSS,也有很多人称为固体放电管,它主要应用场景在于信号线路的雷击浪涌防护。TSS半导体放电管与常见的几种放电管(GDT陶瓷气体放电管、SPG玻璃放电管)有所不同,它是一种利用晶闸管原理制成的过压保护器件,主要依靠PN结的击穿电流触发器件的导通和放电。

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。
【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。
