ABSTRACT:
A semiconductor thyristor, having a given forward voltage drop, has its turn-off time or the reverse current behavior adjusted in a defined manner and a reduced blocking current. Essentially, the semiconductor element is divided, at its anode end, into zone elements having a high and a low concentration of recombination centers, whereby, at the anode end, zones not oppositely disposed from the emitter receive a lower average concentratin of recombination centers. The invention is most advantageous when applied to power thyristors.
