Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS compliance details as specified in official documentation. Check for alternative sourcing channels since standard availability may be limited. Ensure packaging integrity matches bulk specifications. Validate datasheet revisions before integration into new designs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and controlled switching speed are required. The integrated base allows for faster turn-off times compared to standard variants. Consider thermal dissipation limits of 260 mW during operation. Ensure input current does not exceed 90 mA to maintain reliability. Verify package compatibility with existing PCB layouts.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 series of transistor output optocouplers. It is produced by onsemi, which acquired Fairchild Semiconductor. The device is designed for general-purpose isolation tasks where moderate speed and high voltage isolation are critical. It serves as a bridge between low-voltage control circuits and high-voltage power stages.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Check for direct pin-compatible substitutes from onsemi or other manufacturers. Verify that replacement parts meet the same 70 V Bvceo and 5300 Vrms isolation requirements. Ensure current transfer ratio and switching times are comparable. Confirm package type remains PDIP-6.
