Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
In a thyristor with a semiconductor element, which includes a main thyristor and at least one auxiliary arrangement which amplifies the control current, the main thyristor having a main emitter and the auxiliary arrangement having an auxiliary emitter, and a base which is common to the main thyristor and the auxiliary arrangement, with pn-junctions lying between the base and the emitters, emitter electrodes being disposed on the emitters, and a control electrode connected to the base wherein the edge lengths of the emitters of the main thyristor and the auxiliary arrangement have ratio such that the current i e is greater than i u , where i e is determined by the product of the emitter edge length and the line current density j e which has a value in the range between 0.3 and 1.0 amperes per milimeter of emitter edge length, and the current i u is that load current at which the voltage across the thyristor has fallen to 10% or less of the breakover voltage.
