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 fourchannel CNZ3734, and A type of these models with increased collector to emitter breakdown voltage (VCEO > 350V).

Features

High collector to emitter breakdown voltage : VCEO > 300 V,

A type : VCEO > 350 V

High current transfer ratio with Darlington phototransistor output : CTR = 4000% (typ.)

High I/O isolation voltage : VISO ³ 5000 Vrms

Small DIL package for saving mounting space

UL listed (UL File No. E79920)

A-type models have a guaranteed internal insulating distance of 0.4 mm
