Abstract

An example power device includes a semiconductor chip and an arrester element configurable to, in response to a voltage across the arrester element being greater than a threshold voltage, create a current path around an isolation layer configured to electrically isolate the semiconductor chip from a heat sink configured to dissipate heat generated by the semiconductor chip. In this example power device, the threshold voltage is less than a breakdown voltage of the isolation layer.
