Abstract

Some exemplary embodiments of high voltage cascoded III-nitride semiconductor package with a stamped leadframe have been disclosed. One exemplary embodiment comprises a III-nitride transistor having an anode of a diode stacked atop a source of the III-nitride transistor, and a stamped leadframe comprising a first bent lead coupled to a gate of the III-nitride transistor and the anode of the diode, and a second bent lead coupled to a drain of the III-nitride transistor. The bent leads expose respective flat portions that are surface mountable. In this manner, reduced package footprint, improved surge current capability, and higher performance may be achieved compared to conventional wire bonded packages. Furthermore, since multiple packages may be assembled at a time, high integration and cost savings may be achieved compared to conventional methods requiring individual package processing and externally sourced parts.
