现如今，GDT放电管在防雷设备的防护应用可以说是越来越广泛了。那么，你了解GDT放电管吗？本文优恩半导体将带您深入了解一下GDT放电管的结构和特点。

GDT放电管(陶瓷气体放电管)是用于设备输入端的高压保护元件，如果两端电压高于保护规范值，内部会发生短路，输入过电压会被吸收。

GDT放电管的结构和特点

开放式GDT放电管放电路径的电气特性主要取决于环境参数，因此无法保证运行的稳定性。为了提高GDT放电管的工作稳定性，目前的GDT放电管大多采用金属化陶瓷绝缘体和电极进行焊接技术，以保证密封外壳的气密性和放电间隙。气体的种类和压力创造了条件，GDT放电管的充电电极一般有氖气或氢气。

GDT陶瓷气体放电管的各种电气特性，如直流击穿电压、冲击击穿电压、浪涌电流、工频电流电阻和使用寿命等，都可以根据所用系统的要求进行调整和优化，这种调整通常通过改变气体类型、压力、电极涂层材料成分和放电管中电极之间的距离来实现。

从结构上讲，GDT放电管可以看成是一个电容很小的对称开关。正常工作状态下是关闭的，其极间电阻在兆欧级以上。当瞬态浪涌电压超过电路系统的耐压强度时，放电管被击穿时会发生电弧放电，但由于电弧电压低，只有十伏，所以器件可以在短时间内限制浪涌电压的进一步上升。GDT放电管就是利用上述原理来限制浪涌电压，保护电路免受过压的损害。

GDT放电管主要用于保护通信系统、交通信号系统、计算机数据系统和各种电子设备的外部电缆和电子仪器的安全运行。 GDT放电管也是保护电路免受雷击和瞬态过电压的保护元件。

陶瓷气体放电管(GDT)具有载流能力大、响应时间快、电容小、体积小、成本低、性能稳定、寿命长等特点；缺点是点火电压高，在直流电压下不能恢复截止状态，不能用来保护低电压。每次受到瞬态电压时，电路的性能都会下降。

综上所述，本文已经解释了放电管是什么，相信大家对它是什么都有了越来越深的理解。

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。
