Claim:
1. A diode integrated on a chip of semiconductor material having an anode surface and a cathode surface opposite to each other, the diode comprising: a cathode region having a doping of a first type, the cathode region extending from the cathode surface in the chip, a drift region having a doping of the first type with a dopant concentration lower than a dopant concentration of the cathode region, the drift region extending between the anode surface and the cathode region, a plurality of anode regions having a doping of a second type, each anode region extending from the anode surface in the drift region, a cathode electrode of electrically conductive material on the cathode surface and electrically coupled with said cathode region, and an anode electrode of electrically conducting material, wherein:
