Abstract

In the case of a symmetrically constructed TRIAC, which comprises a semiconductor substrate (20) with an internal n-base layer (9), two adjoining p-base layers (7, 11), two n-emitter regions (4, 12) let into the p-base layers (7, 11), two main electrodes (1, 17) arranged on the principal faces (29, 30), and two firing devices, a simplified control is achieved by means of MOS-controlled short circuits (3, 5, 6, 7 or 11, 13, 14, 16) at the n-emitter regions (4 or 12).
