Procurement Notes

Verify the specific suffix /86A against official Vishay documentation to confirm tape-and-reel packaging quantity and orientation. Ensure the order matches the exact part number including all alphanumeric designators to avoid receiving variants with different electrical tolerances or packaging formats. Cross-reference the manufacturer's latest datasheet for any updates on lead times or availability status before finalizing procurement plans.

Selection Notes

Select this component when a compact, high-current rectifier is required for low-voltage applications. The SOD-123FL package is ideal for space-constrained designs. Verify that the 40V reverse voltage rating exceeds the peak inverse voltage in the target circuit. Consider thermal management requirements based on the expected forward current and ambient operating conditions to ensure reliable long-term performance.

Part Context

This diode belongs to Vishay's general-purpose rectifier family, specifically optimized for surface-mount technology. It complements other small-signal and power diodes in the portfolio, offering a balance between current handling capacity and physical size. The M3 suffix indicates compliance with RoHS directives and absence of hazardous substances, aligning with modern environmental standards for electronic components.

Replacement Considerations

Consult official substitution guides for equivalent parts from Vishay or other manufacturers. Ensure replacement diodes match the 1A current rating, 40V reverse voltage, and SOD-123FL package dimensions. Verify that alternative components meet the same thermal and electrical performance criteria for the specific application environment.
