The IS3052 is an optically coupled isolator consisting of a Gallium Arsenide infrared emitting diode coupled with a light activated silicon bilateral switch performing the functions of a triac mounted in a standard 6 pin dual-in-line package. The IS3052 provides random phase control of high current triacs or thyristors. The IS3052 features greatly enhanced static dv/dt capability to ensure stable switching performance of inductive loads.
