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.
