  • 4N25 Optocoupler Phototransistor IC DIP-8 Package

The 4N25 family is an industry standard single channel phototransistor coupler. This family includes the 4N25/4N26/4N27/4N28. Each optocoupler consists of galliumarsenide infrared LED and a silicon NPN phototransistor. These couplers are underwriters laboratories (UL) listed to comply with a 5300 VRMS isolation test voltage. This isolation performance is accomplished through special Vishay manufacturing process. Compliance to DIN EN 60747-5-5 partial discharge isolation

specification is available by ordering option 1.These isolation processes and the Vishay ISO9001 quality program results in the highest isolation performance

available for a commercial plastic phototransistor optocoupler. The devices are also available in lead formed configuration suitable for surface mounting and are available either on tape and reel, or in standard tube shipping containers
