Abstract
A high voltage solid-state switch, which provides bidirectional blocking, consists of a first p- type semiconductor body on an n type semiconductor substrate. A p+ type anode region and an n+ type cathode region exist in portions of the semiconductor body. A second p type region of higher impurity concentration than the semiconductor body surrounds the cathode region. The anode region and second p type region are separated from each other by a portion of the semiconductor body. The semiconductor substrate, which acts as a gate, has an electrode connected thereto. Separate electrodes are connected to the anode and cathode regions.
