A thyristor is preferably fabricated as a single thyristor device in an integrated circuit. The thyristor is made conductive by applying an ordinary gating voltage to the gate thereof. However, the thyristor can be kept in a conductive state, even though a current flowing through the anode and cathode thereof is stopped, if the current is restored to flow through it again within a predetermined short time after has stopped. The thyristor is composed of a first transistor and a second transistor (both of which are also used in a typical thyristor component) a third transistor which forms a Darlington connection with the second transistor, a resistor which is connected between the base and the emitter of the third transistor, and a capacitor which is connected between the base of the second transistor and the emitter of the third transistor. |
