Abstract

The invention relates to a controllable semiconductor circuit element consisting of a vertical thyristor comprised of four zones of alternating conductivity types and arranged in a semiconductor disk, with the two load current connections located on the top surface and on the bottom surface of the semiconductor disk respectively. According to the invention, the semiconductor disk comprises an additional controllable circuit element with a lateral zone structure on the top surface of the semiconductor disk. Zones of this additional circuit element are linked with zones of the vertical thyristor in such a way as to enable the vertical thyristor to be indirectly ignited by ignition of the lateral circuit element.
