Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the date code indicates manufacturing with Green Molding Compound if halogen-free compliance is strictly required. Ensure the procurement channel is authorized to guarantee product authenticity and traceability according to manufacturer guidelines.

Single Zener Diodes Selection Notes

Select this component when a compact SOT-323 footprint is required for 3.6 V regulation. Consider the 200 mW power dissipation limit and thermal resistance of 625 °C/W for heat management. Verify that the 24 Ω impedance meets circuit requirements at the specified operating current.

Single Zener Diodes Part Context

This part belongs to the MMBZ5221BW through MMBZ5259BW series of surface mount Zener diodes. The series offers various voltage ratings from 2.4 V to 39 V in a standardized small outline package. All variants share similar mechanical and electrical testing parameters defined in datasheet DS31037.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 3.6 V nominal voltage, SOT-323 package, and 200 mW power rating. Verify compatibility regarding Zener impedance and leakage current specifications before integration.
