Abstract:
A semiconducting structure comprising:a semiconducting structure forming a protected rectifying bridge implemented in an N-type semiconductor substrate divided into first, second, and third wells by vertical P-type isolating walls, in which a rear surface of the substrate is coated with a first metallization and in which each of the first and second wells includes a vertical diode and a vertical Shockley diode, the first metallization in contact with anodes of the vertical diodes and cathodes of the Shockley diodes,wherein the third well includes a P-type isolating layer on its rear surface side in contact with the first metallization and, on its front surface side, two lateral diodes, each of which is formed between a P-type region and the substrate, each of the two lateral diodes having a cathode and an anode in contact with metallizations.
