Description
The 4N25 family is an Industry Standard Single Chan-
nel 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 volt-
age. This isolation performance is accomplished
through special Vishay manufacturing process.
Compliance to DIN EN 60747-5-2(VDE0884)/ DIN EN
60747-5-5 pending partial discharge isolation specifi-
cation is available by ordering option1.
These isolation processes and the Vishay ISO9001
quality program results in the highest isolation perfor-
mance available for a commercial plastic phototrans-
istor optocoupler.
The devices are also available in lead formed config-
uration suitable for surface mounting and are avail-
able either on tape and reel, or in standard tube
shipping containers.
