a semiconductor component has a semiconductor body comprising a blocking pn junction , a source zone of a first conductivity type connected to a first electrode and bordering on a zone forming the blocking pn junction of a second conductivity type complementary to the first conductivity type , and a drain zone of the first conductivity type connected to a second electrode . the side of the zone of the second conductivity type facing the drain zone forms a first surface , and in the region between the first surface and a second surface located between the first surface and the drain zone , comprises areas of the first and second conductivity type nested in one another . the second surface is positioned at a distance from the drain zone such that the areas of the first and second conductivity type nested in each other do not reach the drain zone .
