Abstract: A thyristor is constituted by a body having at least four alternately P conducting and N conducting layers with two main electrodes for the load current; one of the layers has a connection for ignition current; one part of the body has a blocking voltage lower than that of the other parts; an auxiliary contact applied on such part is connected to the ignition current connection so that, when the blocking voltage of such part is exceeded, current is supplied to the ignition current connection.
