    Abstract: A thyristor circuit includes a first thyristor with first and second emitter layers and two base layers arranged therebetween. The first emitter layer has two separate parts. The first part is provided with a connection for the load current of the thyristor. A second thyristor is connected between the second part of the first emitter layer and the load current connection to the first part. The breakover voltage in the forward direction of the series connection of the second thyristor and the partial thyristor composed of the second part of the first emitter layer and the other layers of the first thyristor is lower than the breakover voltage of the first thyristor. As a result, upon increase of off-state voltage the second thyristor breaks over first with the production of a simultaneous ignition over a large surface.
