EL357N Optocoupler IC - SOP-4 SMD Package

The EL357N(C)(TA)-G is a high-performance optocoupler IC manufactured by Everlight, featuring a single-channel configuration with a phototransistor output. Designed for digital signal isolation and low-speed data communication, it integrates an infrared LED and a phototransistor inside a compact SOP-4 SMD package. With a high isolation voltage of 3750 Vrms and a wide current transfer ratio (CTR), this optocoupler is ideal for power supplies, relays, AC adapters, and microcontroller interfacing in noisy environments. The EL357N ensures robust performance while maintaining minimal board space.
