Abstract
The destruction-free rapid dismantling of current of power semiconductor components can be substantially enhanced when the inhibiting pn-junction is produced with a polished surface of the semiconductor body. The pn-junction thus becomes so uniform that local overloads are avoided. As a result, the speed of the dismantling of the current of the power semiconductor can be increased.
