Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the intended application environment aligns with the specified thermal limits and avalanche ratings. Cross-reference the part number with the latest datasheet revisions to validate any potential design changes or updates prior to final procurement decisions.

Selection Notes

Select this component when a surface-mount fast recovery diode with automotive certification is required. The 1.5 A current rating and 400 V blocking voltage suit moderate power applications. Consider the 140 ns recovery time for efficiency in switching regulators. Verify that the SMA package fits the available PCB real estate and thermal management strategy for the target system.

Part Context

This part belongs to the BYG series of glass-passivated surface-mount fast recovery rectifiers by Vishay. The series offers various voltage ratings within the SMA footprint. The A/H suffix typically denotes specific tape-and-reel packaging options. These devices are designed to replace bulkier through-hole alternatives in modern electronics manufacturing processes.

Replacement Considerations

Consult official substitution guides for compatible parts within the same voltage and current class. Ensure any alternative maintains the required AEC-Q101 qualification if used in automotive contexts. Verify pinout compatibility and thermal performance metrics before implementation.
