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.
• Logic coupling with high frequency noise rejection
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.
AGENCY APPROVALS
• UL file no. E52744
• cUL tested to CSA 22.2 bulletin 5A
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.
• DIN EN 60747-5-2 (VDE 0884)/DIN EN 60747-5-5
(pending), available with option 1
• BSI: EN 60065, EN 60950-1
These isolation processes and the Vishay ISO9001 quality
program results in the highest isolation performance available
for a commercial plastic phototransistor optocoupler.
• FIMKO
• CQC
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.
