Abstract: The unidirectional commutation or switch circuit comprises a thyristor (GTO) with its trigger polarized off in the commutator block (5). There is a capacitor (C') in parallel with a controlled transistor (T), supply terminals (2,3), and the load (1). The controlled transistor (T) is a bipolar transistor, and a resistor (R1) connected between the anode and cathode triggers of thyristor. The transistor base is connected via a reference diode (Z) to the midpoint of a resistor bridge (R2,R3). A bidirectional communication circuit can be constructed by two unidirectional commutation circuits in antiparallel connection. The commutation circuit can be realized in monolithic form on a semiconductor substrate, according to two embodiments. In the monolithic realizations the first zone comprises the thyristor (GTO) in lateral form with the cathode trigger controlled transistor (T) and the diode (Z). The collector of transistor (T) of npn type is connected to a strongly doped region of n type, or to an n type metallized ring.
