Abstract
A diode is disclosed. One embodiment provides a semiconductor body having a front and a back, opposite the front in a vertical direction of the semiconductor body. The semiconductor body contains, successively in the vertical direction from the back to the front, a heavily n-doped zone, a weakly n-doped zone, a weakly p-doped zone and a heavily p-doped zone. In the vertical direction, the weakly p-doped zone has a thickness of at least 25% and at most 50% of the thickness of the semiconductor body.
