A power diode includes at least one semiconductor body having an inner zone f a first conductivity type and a given doping level, a cathode zone of the first conductivity type and a doping level higher than the given doping level, and an anode zone of a second conductivity type opposite the first conductivity type and a doping level higher than the given doping level. The inner zone has at least a first region with a first predetermined thickness being dimensioned for a required blocking voltage and a second region with a second thickness being greater than the first predetermined thickness by at least a factor of 1.4. The area and/or the minority carrier life of first and second partial diodes is dimensioned for causing a current flowing through the first partial diode in a conductive phase to be greater than a current flowing through the second partial diode by at least a factor of 2.

Power diode

A method for mounting semiconductor bodies on a substrate includes bonding ires to a substrate being formed of metal at least in given locations. Semiconductor bodies are laterally fixed to the given locations of the substrate with the wires. The semiconductor bodies are subsequently materially joined to the substrate in the given locations.
