Abstract

The vertical-conduction electronic power device is formed by a body of wide band gap semiconductor which has a first conductivity type and has a surface, and is formed by a drift region and by a plurality of surface portions delimited by the surface. The electronic device is further formed by a plurality of first implanted regions having a second conductivity type, which extend into the drift region from the surface, and by a plurality of metal portions, which are arranged on the surface. Each metal portion is in Schottky contact with a respective surface portion of the plurality of surface portions so as to form a plurality of Schottky diodes formed by first Schottky diodes and second Schottky diodes, wherein the first Schottky diodes have, at equilibrium, a Schottky barrier having a height different from that of the second Schottky diodes.
