Lateral dual channel emitter switched thyristor employing segmented p-base

Abstract

A new lateral dual channel emitter switched thyristor employing segmented p-base, entitled the lateral SB-DCEST, is proposed in order to eliminate the snap-back and to decrease the forward voltage drop. The forward I-V characteristics of the fabricated lateral SB-DCEST show that the snap-back problem is almost eliminated and a lower forward voltage drop by 1 V is obtained when compared with the conventional lateral DCEST due to the enhanced thyristor operation.
