ABSTRACT:
The present invention relates to a stack device comprising a stack of gate turnoff thyristors GTO, of freewheel diodes DRL, and of diodes D, for a semiconductor circuit, said stack device including power supply electrical connection terminals +HT and -HT, and an output terminal PM, together with electrical connection terminals Cs and Cc between said diodes Ds and Dc and a protection circuit P, wherein the geometrical organization of the wiring of said electrical connection terminals +HT, PM, and -HT is predetermined so as to enable the disposition of said thyristors GTO and of said freewheel diodes in said stack to be modified in order to obtain different electrical functions for the semiconductor circuit.
