ABSTRACT:
The present invention relates to a power semiconductor device comprising a switching power semiconductor element, and a free wheeling diode in anti-parallel connection to the switching power semiconductor element. The power semiconductor is characterized in that a reverse electrode of the switching power semiconductor element and a reverse electrode of the free wheeling diode are bonded and mounted on a circuit pattern formed on the main surface of the first substrate, and that a circuit pattern, which is so formed on the main surface of the second substrate as to oppose a surface electrode of the switching power semiconductor element and a surface electrode of the free wheeling diode, is connected to the surface electrodes of the switching power semiconductor element and the free wheeling diode through connective conductors to be soldered, respectively.
