Abstract:
A semiconductor device includes a thyristor disposed in a semiconductor body. The thyristor has an anode, a cathode, a first bipolar transistor located on an anode side, and a second bipolar transistor located on a cathode side. The first and second bipolar transistors are nested and connected between the anode and the cathode. A MOS transistor is disposed in the semiconductor body. The MOS transistor is coupled between a collector region and an emitter region of the second bipolar transistor. The MOS transistor has a gate region connected to the cathode via a resistive semiconductor region that incorporates at least a part of a base region of the second bipolar transistor.

Claim (Index 21):
The semiconductor device according to  claim 18 , wherein the semiconductor body comprises:\n a first semiconductor region having a first conductivity type and including a base region of the first bipolar transistor and also a collector region of the second bipolar transistor; a second semiconductor region having a second conductivity type opposite to the first conductivity type, incorporating the resistive semiconductor region, the base region of the second bipolar transistor and a collector region of the first bipolar transistor, wherein a gate region extends at least over the base region of the second bipolar transistor; a third semiconductor region having the second conductivity type and including the anode and an emitter region of the first bipolar transistor; a fourth semiconductor region having the first conductivity type and including the cathode and an emitter region of the second bipolar transistor; a first metallization electrically connecting the gate region to a first location of the second semiconductor region; and a second metallization electrically connecting a second location of the second semiconductor region to the fourth semiconductor region, a part of the second semiconductor region located between two locations forming the resistive semiconductor region.
