Abstract

A triggerable bidirectional semiconductor device has two terminals and at least one gate. The device comprises, within a layer of silicon on insulator, a central semiconductor zone incorporating the at least one gate and comprising a central region having a first conductivity type, two intermediate regions having a second conductivity type respectively arranged on either side of and in contact with the central region, two semiconductor end zones respectively arranged on either side of the central zone, each end zone comprising two end regions having opposite types of conductivity, in contact with the adjacent intermediate region, the two end regions of each end zone being mutually connected electrically in order to form the two terminals of the device.
