Abstract

PURPOSE:To operate the photothyristor with high dV/dt and high sensitivity, by connecting a transistor controlled by the phototransistor, between the gate and cathode of the photothyristor which is turned on by an optical signal. CONSTITUTION:When a light beam is not emitted from the light emission diode 1, a base current flows into the base of the transistor 6 through the current control element 8, the transistor 6 is turned on, and the gate and cathode of the photothyristor 3 is short-circuited. Accordingly, as for the photothyristor 3, dV/dt becomes extremely high since the grid and cathode is short-circuited. Subsequently, when an optical signal 2 is output from the light emission diode 1, the phototransistor 7 is turned on, and the base and emitter of the transistor 6 is short-circuited. Therefore, the transistor 6 is turned off, and the gate and cathode of the photothyristor 3 are released. Accordingly, the gate trigger sensitivity IFT of the photothyristor 3 becomes extremely high.
