Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'R2' corresponds to reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or component markings. Ensure the supplier provides valid traceability documentation matching the onsemi manufacturing origin. Cross-reference the part number against current obsolescence notices to confirm active production status before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component for applications requiring high gain with minimal input current. The split Darlington architecture suits high-speed digital isolation needs. Compare performance against standard phototransistor outputs if lower speed is acceptable. Verify voltage ratings match system isolation requirements. Consider thermal dissipation limits within the SOIC-8 package for dense layouts.
