EL817C Optocoupler - DIP-4

The EL817C is a high-performance optocoupler designed for reliable electrical isolation between input and output circuits. It integrates an infrared LED and a phototransistor in a compact DIP-4 through-hole package, providing safe signal transfer while protecting sensitive components from high voltage, noise, and ground loop interference.

With an isolation voltage of up to 5,000V, the EL817C is well suited for use in power supplies, industrial control systems, and microcontroller-based circuits where galvanic isolation is essential. Its fast switching characteristics enable accurate signal transmission in feedback, sensing, and control applications. The device operates reliably over a wide temperature range, ensuring stable performance in both consumer and industrial environments.

The EL817C is commonly used for power supply feedback, logic-level isolation, data transmission, and noise-sensitive switching applications. Its simple interface and standard DIP-4 footprint make it easy to integrate into new designs as well as existing PCB layouts.
