Abstract
The distance between an anode and a cathode of a thyristor and the anode and the cathode of a diode formed in a semiconductor protective circuit are made a small as allowable by LSI manufacturing technology, thereby achieving fast starting speed and a low internal resistance when in the conducting condition, so as to limit the rise in voltage on an internal circuit, even when a high-speed pulse is applied.
