Abstract

A semiconductor controlled rectifier comprising an auxiliary thyristor region turned on by a gating signal and a main thyristor region turned on by being gated by the turn-on current flowing through the auxiliary thyristor region, wherein the life time of carriers in the auxiliary thyristor region is made shorter than that of the carriers in the main thyristor region.
