Abstract
A diode is proposed. The diode includes: a semiconductor body having opposing first and second main surfaces; an anode region and a cathode region, the anode region being arranged between the first main surface and the cathode region; an anode pad area electrically connected to the anode region; and trenches extending into semiconductor body from the first main surface. A first group of the trenches includes a first trench electrode. The first trench electrode is subdivided into at least a first part and a second part. A conductance per unit length of the first part along a longitudinal direction of the first trench electrode is by at least a factor of 1000 smaller than a conductance per unit length of the second part along the longitudinal direction of the first trench electrode. The second part is electrically coupled to the anode pad area via the first part.
