Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging options. Ensure the component meets required automotive or industrial qualification standards if applicable to the end-use environment. Cross-reference the package marking codes with official documentation to prevent counterfeit substitution during sourcing.

Selection Notes

Select this component when an 800 V reverse voltage rating and 1 A forward current capacity are required in a compact SMA footprint. Consider the ultra-fast recovery specification for circuits demanding minimal reverse recovery charge. Evaluate thermal management requirements based on the specified surge overload rating and junction temperature limits defined in the technical data.

Part Context
