ABSTRACT:
A bidirectional switch for switching an A.C. voltage at a load, including a monolithic component, formed in an N-type substrate, including a first vertical thyristor; a second vertical thyristor; a P-type triggering region formed opposite to the cathode of the first thyristor and an N-type triggering region formed in the P-type triggering region, the P-type triggering region being intended to receive a control signal in a negative halfwave of the A.C. voltage to trigger the first thyristor; a resistive element connected to the P-type triggering region and to the anode of the first thyristor; and a capacitor having a terminal connected to the N-type triggering region and its other terminal intended to be connected to the reference voltage.
