This family includes the 4N25, 4N26, 4N27, 4N28. Each optocoupler consists of gallium arsenide 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 60747-5-2 (VDE 0884)/ DIN EN 60747-5-5 pending 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 mounti...
