CNY66

Transistor, Photovoltaic Output Optoisolators Overview

The CNY66 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It integrates an NPN phototransistor with a gallium arsenide infrared-emitting diode in a 4-DIP package. Key electrical parameters include a maximum collector-emitter voltage of 32 V, a collector current rating of 50 mA, and a saturation voltage of 300 mV. The device offers a high isolation voltage of 8200 Vrms and supports a forward current up to 75 mA. Current transfer ratios range from 50% to 300% at 10 mA input.
