Classification: CPC H | IPC H

Claim 0:
1. A semiconductor power module comprising;
an insulating substrate having one surface and another surface;
a supporting substrate having a face-surface which faces the one surface of the insulating substrate;
a first switching device, a second switching device and an output side terminal which are arranged on the face-surface of the supporting substrate;
a first power supply terminal arranged on the one surface of the insulating substrate;
a second power supply terminal to which a voltage of a magnitude different from a voltage applied to the first power supply terminal is to be applied, and arranged on the another surface side of the insulating substrate; and
a resin covering a part of the output side terminal, the first power supply terminal and the second power supply terminal,
wherein the first power supply terminal, the first switching device and the output side terminal are electrically connected via a conductor pattern formed on the one surface of the insulating substrate and a conductor pattern formed on the face-surface of the supporting substrate,
the second power supply terminal, the second switching device and the output side terminal are electrically connected via a conductor pattern formed on the another surface of the insulating substrate,
the first power supply terminal and the second power supply terminal which are exposed from the resin are placed with distances from a peripheral edge of the insulating substrate exposed from the resin, and
a direction of a current flowing through the first power supply terminal and a direction of a current flowing through the second power supply terminal are made opposite across the insulating substrate.
