Single Diodes Procurement Notes

Verify the specific ordering code suffix against official Vishay documentation to confirm packaging configuration. The '-18' suffix indicates a 10,000-unit reel format on a 13-inch tape. Ensure that the commercial grade designation aligns with project requirements, as this variant lacks AEC-Q101 automotive qualification compared to HE3_A versions.

Single Diodes Selection Notes

Select this component when a compact SOD-123 footprint is required for standard switching tasks. Consider the thermal resistance values if operating near maximum power dissipation limits. Verify that the 100 V reverse voltage rating exceeds the peak inverse voltage present in the target circuit design to ensure reliable operation.

Single Diodes Part Context

This part belongs to the 1N4148W family of small signal fast switching diodes manufactured by Vishay Semiconductors. It serves as a surface-mount alternative to through-hole variants, offering similar electrical performance in a smaller form factor. The product line includes various packaging options and qualification grades to suit different industrial and consumer electronics needs.

Single Diodes Replacement Considerations

Consult the manufacturer's datasheet for direct cross-reference information. Alternative packages such as SOD-323 may require schematic and layout modifications due to pin spacing differences.
