Abstract
An embodiment of an IGBT comprises an emitter terminal at a first surface of a semiconductor body. The IGBT further comprises a collector terminal at a second surface of the semiconductor body. A first zone of a first conductivity type is in the semiconductor body between the first and second surfaces. A collector injection structure adjoins the second surface, the collector injection structure being of a second conductivity type and comprising a first part and a second part at a first lateral distance from each other. The IGBT further comprises a negative temperature coefficient thermistor adjoining the first zone in an area between the first and second parts.
