Procurement Notes

Verify the specific manufacturer part number against official Diodes Incorporated documentation to confirm exact specifications. Ensure compatibility with required isolation voltages and current transfer ratios for the intended circuit design. Cross-reference datasheet revisions to validate switching times and thermal characteristics prior to final component selection.

Selection Notes

Select this component based on the requirement for a single-channel transistor output optocoupler with surface-mount packaging. Consider the 35 V collector-emitter voltage rating and 5000 Vrms isolation capability when designing circuits requiring galvanic separation. Evaluate the 200% to 400% current transfer ratio range to ensure adequate signal transmission efficiency for the application load.
