Abstract
A semiconductor device includes a first semiconductor die including a normally-off transistor and a second semiconductor die including a plurality of transistor cells of a normally-on GaN HEMT. One of a source terminal and a drain terminal of the normally-off transistor is electrically coupled to a gate terminal of the normally-on GaN HEMT, and the other one of the source terminal and the drain terminal of the normally-off transistor is electrically coupled to one of a source terminal and a drain terminal of the normally-on GaN HEMT. The second semiconductor die further includes a gate resistor electrically coupled between the gate terminal of the normally-off transistor and respective gates of the plurality of transistor cells, and a voltage clamping element electrically coupled between the gate terminal and one of the source terminal and the drain terminal of the normally-on GaN HEMT.
