ABSTRACT:
Controllable power semiconductor components such as, for example, IGBTs and thyristors are provided, which, compared to known components, have a relatively lightly doped n-buffer zone, a relatively flat p-emitter, and an n-base having a comparatively long charge carrier life expectancy. An advantage is achieved that the controllable power semiconductor component has a temperature-independent tail current, despite a low on-state dc resistance and a high blocking voltage.
