摘要

使用功率晶体管作为开关达到其最大集电极-发射极电压能力(BVcex)是可取的。在这种类型的操作中,已经观察到关断过程中的失效现象,并在文献中将其归因于二次击穿、穿孔、穿通、掐断以及各种类型的能级效应。

Transistor Failure Modes in High Power Switching Operation
It is desirable to use power transistors as switches up to their maximum collector-emitter voltage capability (BVcex). In this type operation, failure phenomena during switch-off have been observed and attributed in the literature to second breakdown, punch through, reach through, pinch off, and various types of energy level effects.
