Abstract
A semiconductor component, preferably a thyristor, having emitter short-circuits in the cathode space. The emitter short-circuits are preferably arranged in a uniform fashion about the cathode space and, when formed of a material having <111> oriented crystals are arranged in ternary symmetry about the cathode or in multiples of three. In the case of material having <001> oriented crystals the emitter short-circuits are arranged in a quarternary symmetry or in multiples of four.
