Abstract

An asymmetric snubber resistor in accordance with the present invention includes a cathode, an N+ region, an N- region, a plurality of P+ regions, and an anode. The N+ region is disposed over the cathode, the N- region is disposed over the N+ region, the plurality of P+ regions are disposed over the N- region, and the anode is disposed over the plurality of P+ regions and exposed portions of the N- region. The asymmetric snubber may also include N regions between the P+ regions. The asymmetric snubber resistor replaces the snubber diode and the snubber resistor in a typical snubber circuit.
