CQY80N/CQY80NG is an optocoupler from Vishay Semiconductors, which has UL94-VO grade insulation material, low coupling capacity, high common mode rejection, 55/100/21 climate classification, low temperature coefficient, 6 kV peak transient overvoltage, 1.6 kV insulation voltage, 600 VRMS of insulation voltage, 600 VRMS of recurring peak voltage, 0.75 mm of insulation thickness, and meets RoHS 2002/95/EC and WEEE 2002/96/EC regulations
The CQY80N and CQY80NG series are phototransistor optocouplers in a 6‑pin DIP package, designed for safe electrical isolation in power supplies, line receivers and computer peripheral interfaces. The document provides detailed electrical characteristics, insulation ratings, switching times and mechanical dimensions.
Key features include low coupling capacitance (0.3 pF), high common‑mode rejection, UL‑1577 and IEC safety approvals, and lead‑free RoHS‑compliant construction. The handbook also lists recommended application circuits and environmental ratings.
