Patent ID: 7545033

Claim:
A power module comprising: a support housing; a heatsink; thermally conductive and electrically insulating body in contact with said heatsink; and a lead frame molded in and supported by said support housing, said lead frame including a plurality of spaced conductive pads each unitarily formed with a respective lead that extends from a respective conductive pad to the exterior of said support housing, each conductive pad including a top surface for receiving a power semiconductor switch and an opposing bottom surface in contact with said thermally conductive and electrically insulating body, whereby a portion of heat generated by each said power semiconductor switch is transmitted through said thermally conductive and electrically insulating body and another portion of heat generated by each said power semiconductor switch is transmitted through a respective lead and dissipated outside said support housing, wherein spaces between said conductive pads are filled by portions of said support housing, wherein at least one of said leads is electrically connectable to a power bus to supply power to a connected power semiconductor switch and at least another one of said leads is used as an output external connection.
