What Are Photo Couplers?
Photo Couplers are optoelectronic devices that transfer electrical signals between two isolated circuits using light, ensuring electrical isolation while maintaining signal integrity. They typically consist of a light-emitting diode (LED) and a photosensitive receiver, such as a phototransistor, photodiode, or photo-TRIAC, housed in a single package. Photo Couplers are essential for protecting sensitive electronics from high voltages, noise, and ground loops. At Nikko Electronics, we stock a wide variety of Photo Couplers in through-hole (e.g., DIP, SOP) and surface-mount packages, designed for high isolation voltages, fast switching, and compact integration. Our Photo Couplers are ideal for applications requiring safe and reliable signal isolation.
