Abstract:
1. A diode, comprising: a semiconductor body; a first emitter region of a first conductivity type; a second emitter region of a second conductivity type; a base region arranged between the first and second emitter regions and having a lower doping concentration than the first and second emitter regions; a first emitter electrode only electrically coupled to the first emitter region; a second emitter electrode in electrical contact with the second emitter region; a control electrode arrangement comprising a first control electrode section, and a first dielectric layer arranged between the first control electrode section and the semiconductor body; and at least one pn junction extending to the first dielectric layer or arranged distant to the first dielectric layer by less than 250 nm; wherein the base region has a length in the vertical direction of the semiconductor body that is a shortest distance between the first emitter region and the second emitter region; and wherein a distance between the first control electrode section and the second emitter region is less than 75% of the length of the base region.
