RECEST: a reverse channel emitter switched thyristor

Abstract

A 550 V, reverse channel emitter switched thyristor (RECEST) is demonstrated. It offers ease of thyristor turn-on, a low on-state drop, excellent parasitic thyristor latch-up immunity and a high maximum controllable current density. It is shown to have characteristics superior to both the conventional emitter switched thyristor and the dual lateral channel emitter switched thyristor, and shows promise for use in high-voltage applications.
