Abstract
In a PNPN semiconductor device comprising a cathode base layer, a cathode emitter layer and an auxiliary emitter layer disposed on one of its main faces, an auxiliary electrode is disposed on the cathode base layer adjacent to a cathode electrode and a diode is formed in the cathode base layer between a gate electrode and the auxiliary electrode. The diode includes one semiconductor layer formed of the adjacent portion of the cathode base layer, an electrode connected to the gate electrode and a PN junction forwardly biased with a reverse bias applied to the gate electrode.
