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 V
RMS
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 mounting and are available either on tape
and reel, or in standard tube shipping containers.
Note
• For additional design information see application note 45

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not
implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
maximum ratings for extended periods of the time can adversely affect reliability.
