A THYRISTOR STRUCTURE WITH INTRINSIC SWITCH-ON AND APPLICATION THEREOF TO THE CONTRUCTION OF A BIDIRECTONAL DEVICE

摘要

The thyristor includes a first emitter region and a neighboring, inhibiting main base region. The thyristor also has a second main base region and a second emitter region. The first emitter region is subdivided into several first zones electrically connected to each other by cathode contacts. The first base region is also subdivided into several zones electrically connected to each other through trigger contacts. The trigger contacts are coanected to the cathode contacts by an interruption device alowing a short circuit to be made at the trigger contacts for inhibiting thyristor switch-on.
