ABSTRACT:
A semiconductor switch comprising a PNPN switch which has a four-layered PNPN structure with at least three PN-junctions, switching means for electrically short-circuiting a path between a P-type base and an N-type emitter of the PNPN switch when a transient voltage is applied between a P-type emitter and the N-type emitter of the PNPN switch, and drive means for driving the switching means, the drive means driving the switching means so that the path between the P-type base and the N-type emitter may be electrically short-circuited for a fixed time even after termination of the transient state, whereby any improper ignition of the PNPN switch is prevented even after the termination of the transient state.
