Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability through authorized distributors or secondary markets, as original manufacturing may have ceased. Ensure compatibility with existing board layouts if substituting with newer revisions or alternative manufacturers.

Selection Notes

Select this component for applications requiring high-voltage isolation and moderate current capacity in a compact surface-mount form factor. Consider thermal management requirements associated with the D²PAK package. Evaluate alternative active parts if long-term supply stability is critical for the product lifecycle.

Part Context

This device belongs to Vishay's standard rectifier lineup, offering a balance of voltage rating and current handling in a standardized industrial package. It serves as a common solution for mid-power rectification tasks where space constraints favor surface-mount technology over through-hole alternatives.

Replacement Considerations

Public sources indicate this specific part number is obsolete. Verify equivalent replacements such as the BY229B series from other manufacturers or updated Vishay variants that maintain identical electrical specifications and pinout configurations.
