Abstract
A thyristor having a gate and emitter shunts distributed over a cathode surface, wherein those emitter shunts provided in the vicinity of the gate are separated by shorter distances than those emitter shunts which are present on the remainder of the cathode surface. The distances are in each case determined by measuring the distance from the center of one emitter short-circuit to the center of an adjacent emitter short-circuit.
