Abstract
The invention concerns a pulsed bistable bidirectional electronic switch comprising a monolithic semiconductor circuit formed from a substrate () whereof the rear surface (A) is coated with a metallization connected to earth. Said circuit comprises a vertical bidirectional switch (T, T) provided with a first gate terminal (M), whereof the main electrode (A) on the side of the front surface is connected to a load and an alternating current supply; a horizontal thyristor (T) comprising an upper layer () of the vertical bidirectional switch, a first P-type region (), and a second N-type region () formed in the first region; a second gate terminal (G) 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 (G) and to the alternating current supply (VAC).
