ABSTRACT:
A thyristor has a semiconductor member with a pnpn-layer sequence, a plurality of n(p)-emitter parts, and switching transistors arranged at the edges of the n(p)-emitter parts. The switching transistors respectively include a p(n) semiconductor zone inserted in one of the n(p)-emitter parts, a partial zone of the p(n)-base, and an intermediately disposed channel zone covered by an insulated gate. Rapid and effective reduction of the electron-hole plasma flooding the p-base and n-base during quenching of the thyristor is achieved by a current source connected between electrodes for the p(n) semiconductor zones and a cathode (anode) feed line, the current source delivering an extraction current pulse.
