Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm package dimensions and reel specifications. Ensure that the HM3 designation aligns with required automotive qualification standards. Cross-reference the document number 87168 to access the most recent revision details before finalizing component selection.
Selection Notes
Select this component when high voltage blocking capabilities are required alongside fast switching speeds. The SMF (DO-219AB) package provides a low-profile solution suitable for automated placement processes. Evaluate the thermal resistance parameters to ensure adequate heat dissipation within the target operating temperature range.
Part Context
This part belongs to the eSMP series of ultrafast avalanche rectifiers designed for compact surface-mount applications. The AU1FM variant specifically addresses high-voltage requirements within the family, offering robust performance in space-constrained designs while maintaining compliance with halogen-free and RoHS directives.
Replacement Considerations
Compatible substitutes include AU1FKHM3/H and AU1FJHM3/H, which share identical mechanical footprints and similar electrical ratings within the same product family.
