GDT气体放电管是一种用于保护电子设备的电气保护元件。本文介绍GDT气体放电管主要参数和需要注意的事项。其主要参数包括：

1.额定电压(Rated Voltage)：气体放电管的工作电压范围。

2.漏电流(leakage)：固定电压下，GDT气体放电管的漏电流。

3.动作电压(Strike Voltage)：GDT气体放电管开始带电放电时的电压值。

4.保护电流(Holding Current)：气体放电管正常工作时的电流值。

5.时间到保护电流和电压(Time to Protection Current/Voltage)：气体放电管能够最终启动的保护电流和电压下的反应时间。

使用GDT气体放电管时需要注意以下几点：

1.所选择的GDT气体放电管要满足设计要求，不能超过其最大额定电压和电流。

2.气体放电管通常安装在需要保护的电路入口端，以提供最佳电路保护。

3.GDT气体放电管的带电放电后，会导致其内部电容器被放电，会形成瞬间高压，因此要采取维护好地线和引导电线，并且避免直接接触。

4.不要擅自更改气体放电管的参数或进行拆卸和修理，以避免电气危险。

5.正确选择和使用GDT气体放电管可以大大提高电子产品的耐电压水平，减少电路故障，延长电子产品的使用寿命。
