ABSTRACT:
A vertical thyristor adapted to an HF control, including a cathode region in a P-type base well, a lightly-doped P-type layer next to the base well, a lightly-doped N-type region in the lightly-doped P-type layer, a Schottky contact on the lightly-doped N-type region connected to a control terminal, and a connection between the lightly-doped N-type region and the P-type base well.
