Abstract: Embodiments of a semiconductor device, a circuit including a semiconductor device and a driver circuit, and a method for operating a semiconductor device are described. In one embodiment, a semiconductor device includes a substrate, a source region, a drain region, and a drain extension region formed in the substrate, and an insulation layer adjacent to the drain extension region. A gate layer and a field plate are formed one of within and on the insulation layer. The field plate is located adjacent to the drain extension region and is electrically insulated from the gate layer and the source region such that a voltage can be applied to the field plate independent from voltages applied to the gate layer and the source region. Other embodiments are also described.

Abstract: A circuit for protecting a transistor is disclosed. The circuit includes a temperature sensing device coupled to the transistor and a tunable clamping circuit connected between transistor terminals, wherein the tunable clamping circuit is configured to provide an adjustable clamping voltage. A temperature controller coupled to the temperature sensing device and the tunable clamping circuit is also included. The temperature controller is configured to trigger a change in a clamping voltage of the tunable clamping circuit based on a feedback from the temperature sensing device.
