Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component authenticity upon receipt, as the TPC817B C9G is listed as discontinued in official distributor records. Confirm that the specific C9G suffix matches the required packaging configuration before integration into production lines. Ensure compatibility with existing DIP-4 through-hole mounting processes. Review RoHS directive compliance documentation to verify adherence to current environmental standards for electronic components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard transistor output optocoupler with a minimum current transfer ratio of 130% is required. The 80 V collector-emitter voltage rating supports low-voltage logic interfacing. Verify that the 50 mA collector current capacity meets load requirements. Consider the 4 µs rise time for timing-sensitive digital signal isolation tasks where moderate speed is sufficient.
