CNY17F4VM

Overview

The CNY17F4VM is a single-channel transistor output optocoupler from onsemi, housed in a 6-pin PDIP package. It provides electrical isolation with an insulation voltage of 4170 Vrms. The device features an NPN phototransistor output capable of handling a maximum collector current of 50 mA and a collector-emitter voltage of 70 V. Key electrical parameters include a forward voltage of 1.65 V at a maximum forward current of 60 mA. The current transfer ratio ranges from 160% to 320%. Typical switching times are 6 μs for rise time and 24 μs for fall time. It operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using a phototransistor configuration.
