4N37 Optoisolator Transistor with Base Output (SMD-6 Gullwing) – SMD

This datasheet 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 5000 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.
