• Microcontroller interface circuits
• Power supply feedback loops

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix FR2M against official datasheets to confirm the 6-SMD surface-mount package configuration and tape-and-reel packaging format. Ensure compatibility with automated pick-and-place equipment if used in high-volume manufacturing. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount footprint is required alongside improved switching performance offered by the base-connected phototransistor design. Compare the 4170 Vrms isolation rating against system safety requirements. Evaluate the 70 V collector-emitter voltage limit to ensure it meets the load voltage specifications of the target application circuit without exceeding absolute maximum ratings.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the CNY171 series of transistor output optocouplers from onsemi. The series is designed for general-purpose isolation applications requiring compact packaging. The FR2M designation specifically indicates the surface-mount variant with reel packaging, distinguishing it from through-hole DIP versions within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include CNY171SR2M and CNY171VM, provided the package type and isolation voltage ratings align with the original design constraints. Verify pinout compatibility and thermal characteristics before swapping components in existing layouts.
