Procurement Notes

Verify that the ordering suffix matches the required qualification level. The HE3 suffix indicates RoHS compliance and AEC-Q101 qualification. Confirm the delivery mode corresponds to the specific package code, where 'I' denotes a 7500-unit quantity on a 13-inch diameter plastic tape and reel. Ensure the component revision code aligns with the latest datasheet version to guarantee parameter consistency.

Selection Notes

Select this component when high reverse voltage blocking and fast switching speeds are required in a compact surface-mount form factor. The avalanche rating allows for robust operation during inductive load switch-off events. Consider the thermal resistance values relative to the intended PCB copper area to ensure the junction temperature remains within the specified operating limits during continuous conduction.

Part Context

This part belongs to the BYG23M series of ultrafast SMD rectifiers from Vishay. The series utilizes a glass passivated junction technology designed for high reliability. The specific model integrates automotive qualification standards, distinguishing it from commercial grade variants within the same electrical family. It serves as a specialized solution for demanding power conversion environments requiring both speed and ruggedness.

Replacement Considerations

Direct substitutes within the same electrical specifications and package type include BYG23MHM3_A/I and BYG23MHE3_A/H. Verify that any replacement maintains the required AEC-Q101 qualification status if used in automotive contexts. Ensure the alternative component supports the same 1000 V reverse voltage and 75 ns recovery time constraints.
