Abstract:
1. A semiconductor component comprising: at least two electrodes; and a semiconductor body coupled to the at least two electrodes, the semiconductor body including at least one pn junction and a voltage taking-up region of a first conduction type in which a space charge zone propagates if a voltage that reverse-biases the pn junction is applied to the electrodes, wherein the voltage taking-up region further includes a temporarily effective area of the first conduction type having, between a conduction band and a valence band, centers configured to trap free charge carriers in the event of flooding of the voltage taking-up region, and to discharge the charge carriers in the event of propagation of the space charge zone, such that the area is temporarily effective corresponding to the event of a turn-off operation after flooding with free charge carriers, wherein the temporarily effective area is arranged at a depth of substantially between 0.75 W
