Procurement Notes
Verify the specific ordering suffix matches the required packaging format before procurement. Confirm that the component meets all necessary environmental compliance requirements for the intended deployment region. Ensure that the supplier provides valid traceability documentation consistent with automotive quality standards.
Selection Notes
Select this component when a dual Zener array is required in a compact SOT-323 footprint. Consider the 200mW power dissipation limit and thermal resistance characteristics during circuit design. Verify that the 18V breakdown voltage aligns with the target regulation or protection thresholds.
Part Context
This part belongs to the AZ23CW series of dual Zener diodes from Diodes Incorporated. The series includes variants with different nominal voltages such as 5.6V, 6.8V, and 10V, all sharing the same SOT-323 mechanical outline and general electrical characteristics structure.
Replacement Considerations
Direct replacements within the same family include AZ23C5V6W-7-F, AZ23C6V8W-7-F, and AZ23C10W-7-F. These parts share identical packaging and configuration but differ in nominal Zener voltage ratings.
