ABSTRACT:
A low profile semiconductor device package includes a lead frame with terminal leads and two die pads for receiving at least two semiconductor die that are interconnected to form a circuit. A further low profile semiconductor device package includes a lead frame with two die pads for receiving at least two semiconductor die that are interconnected to form a circuit and also has a reduced height through removal of a mounting tab. An example of such device packages is a package that includes first and second MOSFET die, each connected to a respective die pad. The source of one MOSFET is connected to the drain of the other MOSFET, thereby forming a low profile device package that provides a half-bridge circuit. Other example device packages include different arrangements of two interconnected MOSFET die, two interconnected IGBTs, or a combination of a MOSFET die and a diode.
