Abstract
In a high-power GTO thyristor with anode short-circuits (7) in the anode-side p-type emitter layer (6), the triggering sensitivity is improved by an additional thin and lightly doped p.sup.- -type barrier layer (9) between the anode short-circuits (7) and the n-type base layer (5) without the turn-off process being negatively affected.
