ON3731, Optoisolators

Optoisolators (Photocouplers) CNZ3731, CNC7C501, CNZ3734 CNC2S501, CNC7C502, CNC7H501 Optoisolators Overview The CNZ3731 series of optoisolators consist of a GaAs infrared LED which is optically coupled with a Si NPN Darlington phototransistor, and housed in a small DIL package.

The series provides high I/O isolation voltage and high collector/emitter isolation voltage, as well as a high current transfer ratio (CTR).

This opto isolator series also includes the two-channel CNC7C501 and the fourc
