Description
The 4N29, 4N30, 4N31, 4N32, 4N33 are optically coupled isolators consisting of a Gallium Arsenide
infrared emitter and a silicon photo darlington sensor. Switching can be accomplished while maintaining a
high degree or isolation between driving and load circuits. They can be used to replace reed and mercury
relays with advantages of long life, high speed switching and elimination of magnetic fields. Surface Mount
Option Available.
All electrical parameters are 100% tested by manufacturing. Specifications are guaranteed to a cumulative
