Patent ID: 8436459

Claim:
A power semiconductor module comprising: a lead frame having an upper surface and a lower surface; plural power semiconductor elements disposed on the upper surface of the lead frame; and a cylindrical conductor disposed on the upper surface of the lead frame in electrical and mechanical contact with the lead frame, wherein, a part of the lead frame, the power semiconductor elements, and the cylindrical conductor are sealed with transfer molding resin, the molding resin surrounding the cylindrical conductor, the cylindrical conductor includes a hole exposed at a top surface of the transfer molding resin, and the lead frame includes a first portion having first terminals that protrude from a first peripheral side of the transfer molding resin, and a second portion having second terminals that protrude from a second peripheral side that is opposite to the first peripheral side of the transfer molding resin, each portion forms a continuous structure from an area located underneath one of the power semiconductor elements to a corresponding one of the first and second terminals, respectively, and the first and second portions of the lead frame are discontinuous from each other.
