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
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.
APPLICATIONS
• AC mains detection
• Reed relay driving
a
silicon NPN
• Switch mode power supply feedback
• Telephone ring detection
• Logic ground isolation
• Logic coupling with high frequency noise rejection
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
AGENCY APPROVALS
• UL1577, file no. E52744 system code H or J, double
protection
• DIN EN 60747-5-2 (VDE 0884)
DIN EN 60747-5-5 pending

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.
