Abstract
The invention concerns a pulsed bistable bidirectional electronic switch comprising a monolithic semiconductor circuit formed from a substrate (1) whereof the rear surface (A2) is coated with a metallization connected to earth. Said circuit comprises a vertical bidirectional switch (T1, T2) provided with a first gate terminal (M3), whereof the main electrode (A1) on the side of the front surface is connected to a load and an alternating current supply; a horizontal thyristor (T3) comprising an upper layer (4) of the vertical bidirectional switch, a first P-type region (11), and a second N-type region (12) formed in the first region; a second gate terminal (G1) connected to one of the first and second regions, the other being connected to earth. A capacitor (C) is connected to the first gate terminal (G3) and to the alternating current supply (VAC).
