Single Diodes Procurement Notes

Verify the specific ordering code SD101BW-HE3_A-08 against official Vishay documentation to confirm AEC-Q101 qualification status and RoHS compliance. Ensure the SOD-123 package dimensions and thermal resistance values match the design requirements. Cross-reference the datasheet revision date to ensure access to the latest electrical characteristics and mechanical data before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a 50 V reverse voltage rating is required alongside low forward voltage drop characteristics. The SOD-123 package provides a compact footprint suitable for space-constrained designs. Consider the AEC-Q101 qualification if automotive reliability standards are necessary. Evaluate the thermal resistance and power dissipation limits relative to the expected operating ambient temperature and board layout conditions.

Single Diodes Part Context

This part belongs to the SD101 series of small signal Schottky diodes manufactured by Vishay Semiconductors. The series includes variants with different reverse voltage ratings: SD101AW (60 V), SD101BW (50 V), and SD101CW (40 V). All share the same SOD-123 package and general structural features, differing primarily in their breakdown voltage specifications and associated leakage current limits under reverse bias conditions.

Single Diodes Replacement Considerations

Direct substitutes within the same family include SD101AW-HE3_A-08 and SD101CW-HE3_A-08, provided the system voltage margins accommodate the respective 60 V and 40 V ratings. Verify that any replacement maintains the SOD-123 package outline and pin configuration to ensure mechanical compatibility without PCB redesign.
