瞬态抑制二极管简称TVS，是一种二极管形式的高效能保护器件。本文主要介绍瞬态抑制二极管的主要参数。

VS管有单向与双向之分，单向TVS管的特性与稳压二极管相似，双向TVS管的特性相当于两个稳压二极管反向串联，其主要特性参数有：

1、反向断态电压(截止电压)VRWM与反向漏电流IR：反向断态电压(截止电压)VRWM表示TVS管不导通的最高电压，在这个电压下只有很小的反向漏电流IR。

2、击穿电压VBR：TVS管通过规定的测试电流IT时的电压，这是表示TVS管导通的标志电压。

3、脉冲峰值电流IPP：TVS管允许通过的10/1000μs波的最大峰值电流（8/20μs波的峰值电流约为其5倍左右），超过这个电流值就可能造成永久性损坏。在同一个系列中，击穿电压越高的管子允许通过的峰值电流越小。

4、最大箝位电压VC：TVS管流过脉冲峰值电流IPP时两端所呈现的电压。

5、脉冲峰值功率Pm：脉冲峰值功率Pm是指10/1000μs波的脉冲峰值电流IPP与最大箝位电压VC的乘积，即Pm=IPP*VC。

6、稳态功率P0：TVS管也可以作稳压二极管用，这时要使用稳态功率。

7、极间电容Cj：与压敏电阻一样，TVS管的极间电容Cj也较大，且单向的比双向的大，功率越大的电容也越大。

二极管的历史和原理

二极管的接合构造现在大有PN结合和肖特基形。前者是半导体和半导体结合，细分有扩散接合形和台地形。后者是半导体和金属之间发生的效果。结合这个语言通常不在二极管里表现。在这里为了容易理解分列在这里。现在，实现小功耗高速性的肖特基接合形被注目，鲁晶半导体生产的SBD具有较大优势。

TVS Diode Selection Tips

TVS diodes are electronic components used to protect sensitive electronic devices from high voltage transients. They can handle overvoltages faster than most other types of circuit protection devices. In the following, Lu Jing Semiconductors introduces several transient suppression diode selection techniques:1, TVS diode rated reverse turn-off VWM should be greater than or equal to the maximum operating voltage of the circuit being protected. If the selected VWM is too low, the device may enter an avalanche or the reverse leakage current will affect the normal operation of the circuit.
