Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'R1V' corresponds to the reel packaging configuration as indicated in distributor listings. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure the supplier source matches onsemi authorized distribution channels to guarantee component authenticity and traceability.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a single-channel optocoupler with moderate speed (3 µs) and high isolation voltage is required. Compare against similar models like HMHA2801A if tube packaging is preferred over reel. Verify that the 80-160% CTR range meets the specific drive requirements of the target application circuit.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HMHA series of transistor output optocouplers from onsemi. It shares architectural similarities with other variants in the family but differs in packaging and specific electrical tolerances. The series is designed for general-purpose isolation applications requiring reliable performance across industrial temperature ranges.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

HMHA2801A is a documented substitute within the same product family, offering identical electrical characteristics but typically in tube packaging rather than reel format. Verify pinout compatibility and packaging dimensions before substitution.
