Abstract
An apparatus includes a junction termination edge, a unipolar power transistor, and an RC snubber. The RC snubber has a capacitor between a poly silicon structure and a semiconductor substrate, and part of the junction termination edge. The capacitor has a p-n junction. The RC snubber has a poly silicon resistor between a source of the unipolar power transistor and a first layer forming the capacitor. The unipolar transistor and the RC snubber are coupled in parallel. The RC snubber and the unipolar power transistor are formed monolithically on the semiconductor substrate.
