Abstract

A power thyristor assembly, includes an insulating and metallized substrate, and a power thyristor having a cathode and gate side facing toward and soldered to the substrate, and an anode side facing away from the substrate, the anode side having an anode and a passivation ditch surrounding the anode, the anode side including a reverse junction, the cathode and gate side including a blocking pn-junction, and the passivation ditch being common to the anode side reverse junction and to the cathode and gate side blocking pn-junction.
