Single Zener Diodes Procurement Notes

Verify authenticity by purchasing only from MCC or authorized distributors. Counterfeit parts lack traceability and quality assurance. Confirm the specific marking code K2 matches the datasheet for MMXZ5252B. Ensure the ordering suffix corresponds to the required reel size and packing type for your manufacturing line. Check export control regulations if applicable to your region.

Single Zener Diodes Selection Notes

Select this component when a 24 V Zener reference is required in a compact SOD-323 footprint. Consider the 200 mW power dissipation limit and derating curve for thermal management. Evaluate the dynamic impedance specifications against circuit noise requirements. Verify that the operating temperature range suits the intended environment. Compare leakage current limits with sensitive application needs.

Single Zener Diodes Part Context

This part belongs to the MMXZ5223B through MMXZ5259B series of 200 mW surface mount Zener diodes. All devices in this family share identical mechanical dimensions, package type (SOD-323), and general electrical ratings such as power dissipation and thermal resistance. They differ primarily in their specific Zener voltage values and corresponding marking codes.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOD-323 packaged Zener diodes with a 24 V nominal voltage and similar power ratings. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent dynamic impedance and leakage current specifications are met for the specific application context.
