Abstract

An electrical circuit device made in integrated monolithic form has low level operating characteristics of a MOS device and high level operating characteristics of a Triac. The structure includes two double diffused MOS transistors which have merged drain regions. At higher voltage and current levels a lateral Triac structure is triggered by the MOS devices. Alternatively, separate terminal contacts can be made to the P and N regions comprising the MOS transistor source and channel regions with the Triac triggered conventionally by an externally applied control voltage.
