Abstract
A voltage-controlled power monolithic bidirectional switch has two main terminals and includes a control electrode whose voltage is referenced to one of the main terminals. The switch includes a lateral P-channel MOS transistor; a vertical N-channel MOS transistor, the source well of the vertical N-channel MOS transistor also constituting the source of the lateral transistor; a lateral thyristor whose first three regions correspond to the source, drain and channel of the lateral MOS transistor; a first vertical thyristor disposed in parallel with the lateral thyristor; and a second vertical thyristor having a polarity opposite to the first polarity and disposed in parallel with the vertical MOS transistor.
