摘要 |
The invention concerns an anode voltage sensor of a vertical power component selected from the group consisting of components called thyristor, MOS, IGBT, PMCT, EST, BRT transistor, MOS thyristor, turn-off MOS thyristor, formed by a lightly doped N-type substrate (1) whereof the rear surface (2) having a metallizing coat corresponds to the component anode. Said sensor comprises, on the front surface side, a substrate zone (12) surrounded at least partly by a P-type region with low potential in front of an anode potential, said zone (12) being coated with a metallizing coat (M) in ohmic contact with it, whereon is provided an image of the anode voltage.
