Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '560E' confirms the surface-mount SMD package variant distinct from through-hole DIP versions. Confirm RoHS compliance status and ensure the supplier provides valid datasheets matching Broadcom Limited specifications. Check for authenticity markers as counterfeit components may exhibit degraded isolation or electrical parameters.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface-mount assembly is required alongside high-voltage isolation needs. The integrated base terminal offers superior switching characteristics compared to standard phototransistors without base leads. Ensure the application voltage does not exceed the maximum collector-emitter rating and that current transfer ratio requirements align with the specified minimums at operating temperatures.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY17 family of transistor output optocouplers, widely used in industrial and consumer electronics for galvanic isolation. The '4' designation typically indicates the inclusion of a base lead on the output transistor, while '560E' specifies the surface-mount packaging format. This series is designed to replace older through-hole variants in compact PCB designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible alternatives include other CNY17 series variants with base leads such as CNY17-4-300E for through-hole applications if reflow soldering is not feasible. Verify that substitute parts maintain equivalent isolation voltage ratings and current transfer ratio ranges to ensure circuit functionality remains unchanged.
