TECHNICAL DESCRIPTION
This invention describes an anode voltage sensor of a vertical power component selected from the group of components called thyristors, MOS, IGBT, PMCT, EST, BRT transistor, MOS thyristor, turn-off MOS thyristor, formed by a lightly doped N-type substrate such that the rear surface has a metallic coat that corresponds to the component anode. The front surface side of sensor has a substrate zone surrounded at least partly by a P-type region with low potential in front of an anode potential. This zone is coated with a metallizing coat that is in ohmic contact providing an image of the anode voltage.
