Patent ID: 8653534

Claim:
A Schottky diode, comprising: a drift region having a first conductivity type; a Schottky contact on the drift region; a plurality of junction barrier Schottky (JBS) regions at a surface of the drift region adjacent the Schottky contact, the plurality of JBS regions having a second conductivity type opposite the first conductivity type; and a surge protection region at the surface of the drift region adjacent the Schottky contact, the surge protection region comprising a plurality of surge protection subregions having the second conductivity type; wherein the surge protection subregions are configured such that a voltage drop from a surface of the drift region to a center of a junction between one of the surge protection subregions and the drift region is sufficient to cause the junction to become forward biased at a forward current that is higher than a rated current of the Schottky diode so as to provide a current surge handling ability in the Schottky diode.
