Abstract
A bidirectional protection component comprises two reverse connected thyristors, each of which is in anti-parallel with a diode, the gates of the two thyristors being interconnected and floating. This component, which can be monolithic comprises two vertical thyristors having the same orientation and two vertical diodes having the same orientation, opposite that of the thyristors. Semiconductor regions (P3, N2, P1) constituting the thyristors are common except for their cathode regions (N11, N12). The component comprises three metallizations: a rear surface metallization (M1) connecting the common anodes of the thyristors with the cathodes of the diodes, a first front surface metallization (A1) connecting the cathode (N11) of a thyristor to the anode (P21) of a diode, and a second front surface metallization (A2) connecting the cathode (N12) of the other thyristor to the anode (P22) of the other diode.
