'''反向击穿'''的现象发生在很多情况下面，比如[[二极管]]，[[三极管]]等等。以二极管为例：二极管是正向导通的，二极管两端加反向电压时，电子不能通过二极管，使得二极管相当于断路，但是这个断路取决于把二极管反向接时，二极管两端的电压，如果这个反向电压足够大，二极管就被击穿了，此时这个击穿的反向电压就叫[[反向击穿电压]]。以下给出二极管反向击穿电压的理性定义：外加反向电压超过某一数值时，反向电流会突然增大，这种现象称为电击穿。引起电击穿的临界电压称为二极管反向击穿电压。电击穿时二极管失去单向导电性。

*中文名:[[反向击穿]]

*外文名:reverse breakdown

*中文拼音:fan xiang ji chuan

*定    义:反向电压达到极限值时发生的击穿
