Procurement Notes

Verify the specific manufacturer source, as production rights for this component have transferred to onsemi. Confirm that the received part matches the exact suffix requirements for insulation voltage and package color. Check for RoHS compliance status relative to the manufacturing date. Ensure the component is sourced from authorized distributors to avoid counterfeit parts. Validate all electrical parameters against the official datasheet before integration.

Selection Notes

Select this component when a standard DIP-6 form factor is required for through-hole mounting. Choose based on the need for a 4170Vrms isolation rating and NPN phototransistor output. Consider the operating temperature range and current transfer ratio specifications for the specific circuit application. Verify compatibility with existing PCB footprints designed for the CNY17 series.

Part Context

This component belongs to the CNY17 series, which consists of GaAs IREDs coupled with NPN phototransistors. The 'F' designation typically indicates specific current transfer ratio groupings, while 'VM' denotes the white package variant with VDE approval. This series is widely used in general-purpose isolation applications requiring reliable signal transmission across isolated boundaries.

Replacement Considerations

Direct replacements include CNY17F3W for black package variants or CNY17F3M for other packaging options. Verify pinout compatibility and isolation voltage ratings when substituting. Cross-reference with MOC810X devices if form factor constraints allow.
