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 four-
channel 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 ≥ 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
Applications
Telephones
Telephone exchange
FAX
Programmable controllers
