DESCRIPTION
The 4N25 family is an Industry Standard Single Channel Phototransistor Coupler.
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...
