Procurement Notes
Verify component authenticity through authorized MCC distributors or verified platform listings. Confirm the presence of AEC-Q101 certification marks on documentation. Ensure the ordering suffix matches the exact specification requirements. Cross-reference datasheet revisions to confirm compatibility with existing designs.
Selection Notes
Select this component when a dual Zener solution with automotive qualification is required. The 300 mW power rating suits low-current regulation tasks. Verify that the 70 Ohm impedance aligns with noise sensitivity constraints. Ensure the SOT-23-3 footprint fits the target PCB layout constraints.
Part Context
This part belongs to the AZ23C series of dual Zener arrays from Micro Commercial Components. The series offers various voltage options within the same SOT-23-3 package form factor. The HE3 suffix typically indicates specific manufacturing or compliance attributes defined by the manufacturer.
Replacement Considerations
Direct substitutes include other AZ23C24 variants from MCC if package compatibility is maintained. Cross-brand replacements require matching the 24 V Zener voltage, 300 mW power rating, and SOT-23-3 footprint. Verify AEC-Q101 compliance if automotive application continuity is critical.
