Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a heat radiating plate having a circuit area in which at least one semiconductor element is arranged, the circuit area being provided on one main surface;
a pair of terminals that are connected to the at least one semiconductor element, and have fastening holes; and
a resin housing that covers the circuit area of the heat radiating plate to seal the at least one semiconductor element, and has a terminal surface formed on a top surface, a pair of side surfaces in a longitudinal direction, and a pair of front and rear surfaces in a lateral direction, the resin housing having a nut accommodating opening formed on the terminal surface for embedding a terminal nut, wherein
the resin housing has a pair of bending contact portions that come into respectively contact with the pair of terminals to define bending positions of the terminals,
one of the pair of bending contact portions corresponding to one of the pair of terminals and another of the pair of bending contact portions corresponding to another of the pair of terminals are formed to have different heights,
the pair of terminals protrude from the resin housing at positions sandwiching the nut accommodating opening, and are bent so as to overlap each other on the nut accommodating opening,
the fastening holes face the nut accommodating opening,
one of the pair of bending contact portions is a protrusion formed on an edge portion of the terminal surface, and
the edge portion of the terminal surface has a pair of step portions including walls formed downward from an upper end of the terminal surface and surfaces formed between a lower end of the walls and the side surfaces, the pair of terminals protruding from the walls outside the resin housing along the surface of the pair of step portions, and being bent along the walls to be arranged in areas of the pair of the step portions.
