Triac, SCR Output Optoisolators

Triac and SCR output optoisolators allow bi-directional or unidirectional control of an AC (alternating current) source while providing isolation between the control and load circuits. An LED is optically coupled to a photodiode in a single device package. The photodiode controls the gate of the Triac or SCR and may include zero cross circuity. These optoisolators are selected by on-state current, forward voltage, turn on time, and mounting type.
