Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'M' corresponds to the tube packaging variant when sourcing. Confirm that the Darlington output type matches the load requirements, as it differs from standard transistor outputs. Ensure the 5000Vrms isolation rating meets safety standards for the target application voltage. Cross-reference the manufacturer part number with official Lite-On documentation to avoid confusion with similar LTV series components.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high current gain is required without external amplification. The Darlington structure provides significant CTR but may exhibit slower switching speeds compared to single-transistor variants. Consider the 35V maximum collector-emitter voltage limit for low-voltage logic interfacing. Verify thermal management needs given the 200mW power dissipation constraint in enclosed spaces.
