Abstract
In an MOS-controlled power semiconductor component having a multiplicity of cathode cells, the surface area proportion of the cathode cells relative to the total component surface area is selected at between 0.1% and 10% in the case of circular cell geometry and between 0.4% and 40% in the case of strip-shaped cell geometry. As a result of this, the susceptibility to oscillation caused by small inductances can be reduced. (FIG. 1)
