Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component status as the HMHA2801CR2V is listed as obsolete and no longer manufactured by onsemi. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure that any substitute components meet the original specifications for isolation voltage, package dimensions, and electrical characteristics to maintain system integrity.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a small form factor is required alongside standard transistor output isolation. The 3750 Vrms insulation rating supports applications demanding robust safety separation. Consider the 200–400% current transfer ratio for driving subsequent logic stages. Evaluate thermal management capabilities given the 210 mW power dissipation limit at elevated operating temperatures up to 100°C.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the HMHA2801 series of optocouplers, which are designed for general-purpose isolation tasks. The series includes variants such as the HMHA2801 and HMHA2801CR2, differing primarily in current transfer ratio bins and packaging suffixes. The HMHA2801CR2V specifically denotes the tape-and-reel packaging configuration for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Public confirmed substitutes include the HMHA2801AR2V. Verify compatibility regarding pinout, isolation ratings, and electrical parameters before substitution. Other generic replacements may exist but require independent validation against the original datasheet specifications.
