Title: Semiconductor switch circuit
Inventor: INABE YASUNOBU
IPC: H03K17/16
Filed: 1984-11-19
Abstract: PURPOSE:To obtain a surge protecting circuit which has a high response speed in a surge application mode and is easily converted into an IC, by using a semiconductor switch of PNPN 4-layer structure. CONSTITUTION:When the surge is applied at a time point t0, the voltage Vp of a terminal 5 increases in response to the surge voltage Vs. When the Vs reaches a prescribed level, a PNPN switch 9 is turned on. Thus the Vp is re duced suddenly. When the current flowing to the switch 9 increases in response to the increase of the Vs, both a PNPN switch 10 and a transistor 11 are turned on.Then the Vpis slightly reduced (t5). Then the Vp keeps approximately a fixed level. The Vs is reduced and the current of the switch 9 is reduced less than a holding current (t6). Thus the switch 9 is turned off. Hereafter the Vp is reduced in response to the Vs. Thus the response speed is increased in an application mode of surge. Furthermore surge protecting circuit can be converted into an IC since no arrester tube is used.
