CNY17-4M

Transistor, Photovoltaic Output Optoisolators Overview

The CNY17-4M is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an AlGaAs infrared LED emitter with an NPN phototransistor featuring a base terminal for enhanced switching control. The device provides high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +110°C. Key electrical parameters include a maximum collector-emitter saturation voltage of 300 mV, rise and fall times of 10 µs, and a forward voltage of 1.65 V. It is housed in a 6-pin PDIP package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'M' against the manufacturer's current datasheet to confirm pinout and packaging details, as suffixes may indicate variations in tape-and-reel configuration or regional compliance standards. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when base-driven phototransistors are required for faster response times than standard CNY17 variants. Confirm that the 6-pin DIP form factor fits the assembly constraints. Validate that the 5000 Vrms isolation rating meets the safety standards of the target application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of transistor output optocouplers. The series is widely used for general-purpose isolation. The '4' designation typically indicates a specific Current Transfer Ratio (CTR) group, while 'M' often denotes a specific packaging or ordering variant within the Everlight portfolio.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other CNY17-4 variants from different manufacturers such as Lite-On or Vishay, provided they match the 6-pin DIP package and base-connected phototransistor architecture. Verify CTR ranges and isolation voltages match the original design specifications.
