Patent ID: 7656016

Claim:
A power semiconductor device, comprising: at least one pair of power modules including a first power module and a second power module, each of said power modules formed in a separate resin package, each having a substantially flat molding surface covered with molding resin and a radiating surface opposite to the molding surface; and a pair of radiating fins sandwiching said power modules such that the molding surfaces of the resin package of said power modules directly contact each other and the radiating surfaces of the resin package each contact said radiating fins, wherein each of said power modules includes a pair of main terminals and at least one control terminal, and each of said power modules further having first and second side surfaces opposite to each other, wherein the main terminals of said power modules extend from the first side surfaces and have emitter and collector terminals, the emitter terminal of the first power module opposes to the collector terminal of the second power module, and the collector terminal of the first power module opposes to the emitter terminal of the second power module, and the control terminal of said power module extends from the second side surface.
