Abstract
A thyristor with gate-controlled emitter short-circuits designed as MIS structures of which a first part is switched off only for the duration of the ignition operation to form stabilization short-circuits, and a second, larger part is switched on only during quenching operation to form quenching short-circuits. The number of quenching short-circuits is established so that the emitter short-circuits effective during the quenching take up between 10% up to 80% of that part of the cross-sectional surface of the thyristor taken up by the totality of the emitter regions.
