Optoisolators

Optoisolators, also known as optocouplers, transmit signals between electrical circuits while maintaining isolation, protecting sensitive components from high voltages and noise. They consist of an LED and a photodetector, where the LED emits infrared light to transfer the signal without direct electrical contact. Common types include phototransistor and photodiode optoisolators for standard and high-speed applications, triac optoisolators for AC switching, and digital optoisolators for logic-level signals. These devices are widely used in power electronics, communication systems, and industrial automation. At chipmall.com, we offer a variety of optoisolators, including transistor output, triac output, solid-state relays, and gate drive optocouplers, catering to diverse circuit isolation needs.
