Deactivatable thyristor with turn-off current path

摘要

An emitter of a thyristor is divided into a plurality of emitter regions. An electrode is provided next to each of these regions, and a turn-off current path proceeds via this electrode from the base adjoining the emitter region over a first field effect transistor to a main terminal of the thyristor. Every emitter region is also connected to this main terminal via a second field effect transistor which is integrated into the semiconductor body of the thyristor, or is manufactured in thin-film technology.
