Abstract:
1. A power module comprising: a lead frame, said lead frame including a plurality of spaced conductive pads and a plurality of leads; a molded shell, said molded shell including a plurality of walls defining a space and a base portion, said base portion including said spaced conductive pads and a mold body disposed between said spaces; and a plurality of power semiconductor devices each having one power electrode electrically and mechanically attached to a respective first spaced conductive pad by a layer of conductive adhesive, and an opposing power electrode disposed on an opposing surface thereof electrically attached to a second spaced conductive pad by at least one wire bond; said first spaced conductive pads are arranged along one line and said second spaced conductive pads are arranged along another opposing line in a same plane as that of the first spaced conductive pads; wherein a current detection resistor is directly electrically connected to a pair of leads which extend through at least one of said walls to the exterior of said molded shell, and a heatsink is attached to said base portion and in thermal contact with at least said first spaced conductive pads by a thermally conductive adhesive.
