Optocoupler, Phototransistor Output, with Base Connection
4N35-X, 4N36-X, 4N37-X, 4N38
Vishay Semiconductors
DESCRIPTION
This data sheet presents five families of Vishay industry
standard single channel phototransistor couplers. These
families include the 4N35, 4N36, 4N37, 4N38 couplers.
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 Vishay
double molding isolation manufacturing process. Comliance
to DIN EN 60747-5-5 partial discharge isolation specification
is available for these families by ordering option 1.
These isolation processes and the Vishay ISO9001 quality
program results in the highest isolation performance
available for a commecial plastic phototransistor
optocoupler.
The devices are 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 normalized
