Description
This data sheet presents five families of Vishay Indus-
try Standard Single Channel Phototransistor Cou-
plers.These families include the 4N35/ 4N36/ 4N37/
4N38 couplers.
Each optocoupler consists of gallium arsenide infra-
red 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
Vishay double molding isolation manufacturing pro-
cess. Comliance to DIN EN 60747-5-2(VDE0884)/
DIN EN 60747-5-5 pending 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 perfor-
mance available for a commecial plastic phototransis-
tor optocoupler.
The devices are available in lead formed configura-
tion suitable for surface mounting and are available
either on tape and reel, or in standard tube shipping
containers.
Note:
Designing with data sheet is cover in Application Note 45
