4N25 High-Isolation Optocoupler

The Motorola 4N25 is a single-channel optocoupler designed for high-voltage isolation up to 7.5kV. It protects low-voltage control electronics from hazardous potentials while maintaining reliable signal coupling. This makes it suitable for power supplies, industrial controls, and safety interfaces. Engineers trust the 4N25 for its proven isolation performance and straightforward through-hole integration. It supports compliance-driven designs where electrical separation is mandatory. Request a quote today to strengthen isolation in your next project.
