Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix FR2 against official datasheets to confirm the surface-mount variant and reel packaging configuration. Confirm RoHS compliance status and check for obsolescence notices from onsemi prior to finalizing procurement plans. Ensure the supplier provides valid traceability documentation matching the manufacturer's part identification.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when surface-mount technology is required for single-channel isolation applications. The integrated base lead offers superior switching characteristics compared to standard phototransistors without base connections. Consider the 4170 Vrms isolation rating for safety-critical interfaces and verify that the 70 V collector-emitter voltage meets the load requirements of the target circuit design.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the CNY171 series of transistor output optocouplers produced by onsemi. The series is designed for general-purpose isolation tasks in digital and analog circuits. The FR2 suffix specifically denotes the surface-mount gull-wing package variant, distinguishing it from through-hole PDIP versions like the CNY171VM. This family emphasizes reliability and compact form factors for modern electronic assemblies.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Cross-reference with other onsemi surface-mount optocouplers featuring base leads if availability is constrained. Verify pinout compatibility and thermal characteristics before substituting with generic equivalents. Ensure replacement parts maintain equivalent isolation voltage and current transfer ratio specifications.
