Abstract: A circuit for protecting a transistor is enclosed. 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.
