Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the exact suffix configuration against the manufacturer's latest datasheet, as variations such as CNY17-3S(TA)-V may exist. Confirm RoHS compliance status and specific packaging type (Reel vs Cut Tape) directly with the supplier or distributor before ordering. Ensure the component meets all required safety certifications for your target market.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a phototransistor output with a base pin is required for faster switching or better linearity compared to base-less variants. The 100-200% CTR range suits applications needing moderate gain. Verify that the 60 mA maximum forward current and 80 V collector-emitter voltage meet the circuit design constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of transistor output optocouplers. The '3' designation indicates a specific Current Transfer Ratio group (100-200%). The 'S1' denotes the surface-mount DIP package style, while '(TA)' typically refers to tape and reel packaging. The '-V' suffix often indicates RoHS compliance.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements within the same family include CNY17-3S(TA)-V. Other CNY17 variants with different CTR groups (e.g., CNY17-1, CNY17-2) are pin-compatible but offer different gain characteristics. Cross-brand equivalents like PC817 require verification of isolation voltage and CTR specifications.
