  • Patent number: 7298027
    Abstract: A surface mounted package for semiconductor die has a lead frame with a first and elongated die pad which receives three MOSgated die spaced along its length; second, third and fourth die pads laterally spaced from the first die pad and in a row parallel to the first die pad and receiving respective MOSgated die. A central wire bond receiving pad is disposed between the first pad and the spaced second, third and fourth pads. Wire bonds then connect the die into a three phase inverter circuit. Pin connectors extend through a plastic housing covering the top of the lead frame and are connectable, with the die pads, to the surface of a PCB.
