Monolithic semiconductor switch and supply circuit component

摘要

A monolithic semiconductor component has a first thyristor having a gate, an anode and a cathode. The gate is connected to the cathode through a first resistor and to the anode through the series connection of a zener diode and a second thyristor. The thyristors are of the vertical type and the zener diode is of the lateral type. The cathode of the zener diode is connected to the cathode of the second thyristor through a metallization forming an output terminal.
