ABSTRACT:
A photosensitive integrated circuit switch that operates in the same manner as back-to-back photosensitive SCR's. The invention combines the monolithic, junction-isolated construction of the basic photrac, described in U.S. Pat. No. 3,918,083, and the operational characteristics of a dielectrically isolated photrac, described in co-pending application Ser. No. 616,040, but incorporates the single-quadrant gate-triggering feature of the latter. Its simplified construction makes it advantageous in many applications.
