Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number and marking code against official Panjit documentation. Confirm compliance requirements such as RoHS status and specific electrical tolerances prior to integration. Ensure storage conditions align with semiconductor handling standards to maintain performance integrity throughout the supply chain.

Selection Notes

Select this component when a dual Zener solution with a shared anode terminal is required in a compact SOT-23 footprint. The 24 V nominal rating suits applications needing precise voltage regulation or protection at this specific potential level. Consider the 300 mW power dissipation limit and thermal resistance values when designing heat management strategies for dense PCB layouts.

Part Context

This part belongs to the AZ23C2V4 series, which encompasses dual Zener diodes with voltages ranging from 2.4 V to 51 V. All members share identical mechanical dimensions and packaging styles but vary in electrical parameters such as Zener voltage, impedance, and leakage current. The series provides a standardized platform for designers needing multiple regulated voltages in minimal board space.

Replacement Considerations

Direct substitutes within the same series include other AZ23CxVx variants with different voltage ratings but identical pinouts and configurations. Cross-series replacements require verification of package compatibility and electrical parameter alignment. Consult Panjit documentation for updated equivalent part numbers if specific voltage values differ from the original design requirements.
