Abstract

The present invention relates to a semiconducting structure constituting 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 the 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 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.
