Optocouplers / Isolators

As safety products, optocouplers are designed to protect sensitive control circuitry or people from high voltages. They galvanically isolate the low- and high-voltage sides of a circuit by using an infrared emitter to transmit the control signal to a photo detector and reduce electrical noise coupling. Optocouplers from Vishay Intertechnology feature high isolation voltages, wide temperature ranges, and a wide range of output configurations to provide a perfect fit for your application.
