Abstract

A semiconductor device is disclosed. One embodiment includes a first semiconductor die having a normally-off transistor. In a second semiconductor die a plurality of transistor cells of a normally-on transistor are formed, wherein one of a source terminal/drain terminal of the normally-on transistor is electrically coupled to a gate terminal of the normally-on transistor and the other one the source terminal/drain terminal of the normally-off transistor is electrically coupled to one of a source terminal/drain terminal of the normally-on transistor. The second semiconductor die includes a gate resistor electrically coupled between the gate terminal of the normally-off transistor and respective gates of the plurality of transistor cells. A voltage clamping element is electrically coupled between the gate terminal and the one of the source terminal/drain terminal of the normally-on transistor.
