An integrated transistor module includes a lead frame that defines at least one low-side land and at least one high-side land. A stepped portion of the lead frame mechanically and electrically interconnects the low-side and high-side lands. A low-side transistor is mounted upon the low-side land with its drain electrically connected to the low-side land. A high-side transistor is mounted upon the high-side land with its source electrically connected to the high-side land.

An integrated power device module including a lead frame having first and second spaced pads, one or more common source-drain leads located between the first and second pads, and one or more drain leads located on the outside of the second pad. First and second transistors are flip chip attached respectively to the first and second pads, wherein the source of the second transistor is electrically connected to the one or more common source-drain leads. A first clip is attached to the drain of the first transistor and electrically connected to the one or more common source-drain leads. A second clip is attached to the drain of the second transistor and electrically connected to the one or more drain leads located on the outside of the second pad. Molding material encapsulates the lead frame, the transistors, and the clips to form the module.

A semiconductor package assembly including a molded leadless package (MLP) having an exposed top emitter pad and an exposed bottom source pad. A folded heat sink is attached to the exposed top emitter pad of the MLP by a soft solder attach process. The folded heat sink has a planar member generally coextensive in size with the MLP and in electrical and thermal contact with the top emitter pad of the MLP, and also has one or more leads extending generally perpendicularly to the planar member in a direction towards the lower surface of the MLP. These heat sink leads may provide the emitter connection to a printed circuit (PC) board.
