Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging configurations. Ensure the procurement channel provides valid traceability for AEC-Q101 qualified components. Cross-reference the manufacturer part number with the latest datasheet revisions to confirm availability and compliance status before finalizing orders.

Selection Notes

Select this component when designing circuits that require robust avalanche capability within an automotive-grade form factor. The 800 V rating suits high-side or flyback applications where transient suppression is critical. Verify thermal management requirements align with the DO-220AA package capabilities for the intended operating environment.

Part Context

This device belongs to the eSMP series from Vishay, which focuses on small-outline packages for space-constrained designs. The AS1P prefix indicates an avalanche-rated single diode variant. It complements standard rectifiers by offering specific ruggedness against overvoltage events in regulated power supplies.

Replacement Considerations

The AS1PGHM3/85A is noted as functionally similar but may involve different screening levels. Verify if the alternative meets the specific AEC-Q101 requirements needed for the target application.
