Procurement Notes

Verify the complete part number including the suffix before ordering. Confirm that the commercial grade qualification meets project requirements, as automotive versions require specific Q-suffix designations. Ensure the procurement channel is authorized to guarantee product authenticity and adherence to standard terms and conditions.

Selection Notes

Select this component when a dual Zener solution in a common anode topology is required. Verify that the 300 mW power rating and thermal resistance are sufficient for the intended ambient temperature conditions. Check that the 2.8 V to 3.2 V voltage range aligns with circuit specifications and that the SOT-23 footprint matches the PCB layout constraints.

Part Context

This component belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage options from 2.7 V to 51 V, all sharing the same physical package and general electrical characteristics. The AZ23C3V0-7-F specifically addresses low-voltage dual regulation needs within this standardized family.

Replacement Considerations

Direct replacements include other AZ23C3V0 variants such as the automotive-grade AZ23C3V0Q-7-F. Cross-manufacturer equivalents must be verified against pinout, voltage tolerance, and impedance specifications to ensure functional compatibility without redesigning the host circuit.

FAQ

What is the maximum reverse leakage current for the AZ23C3V0-7-F?

The datasheet does not specify a maximum reverse leakage current value for the AZ23C3V0 variant; it is only listed for higher voltage types in the series.

Is the AZ23C3V0-7-F qualified for automotive applications?

No, the -7-F suffix indicates commercial grade qualification. Automotive applications require parts with the Q-suffix, which are qualified to AEC-Q101 and manufactured in IATF 16949 certified facilities.

What is the typical total capacitance of the AZ23C3V0-7-F?

The datasheet provides a graph for typical total capacitance versus nominal Zener voltage but does not list a specific numerical value for the AZ23C3V0 model.
