Procurement Notes

Verify the complete part number including suffixes such as _A/H against official Vishay documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the required AEC-Q101 automotive qualification aligns with your specific design standards. Cross-reference the DO-214AC footprint dimensions with your PCB layout guidelines prior to procurement to guarantee mechanical compatibility.

Selection Notes

Select this component when a 50 V reverse voltage rating and 2 A continuous current capacity are required in a compact SMA package. The 25 ns recovery time makes it suitable for higher frequency switching applications compared to standard rectifiers. Ensure the application environment stays within the specified -55°C to +150°C operating range. Consider the 35 A surge current rating for transient protection needs in inductive circuits.

Part Context

This device belongs to the BYG series of Super-Ectifier fast recovery rectifiers manufactured by Vishay Semiconductors. The series utilizes glass passivation technology to provide high reliability and low leakage currents. These components are engineered for general-purpose and specialized rectification tasks where fast switching speeds and compact surface mount form factors are critical design constraints.

Replacement Considerations

Check for direct equivalents within the BYG22 series or other Vishay fast recovery rectifiers with matching 50 V/2 A ratings. Verify pinout compatibility and thermal characteristics before substituting with parts from other manufacturers. Ensure any replacement also meets AEC-Q101 requirements if used in automotive contexts.
