Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets the required environmental compliance standards for the target application. Cross-reference the part number with the latest datasheet revision to validate electrical parameters before procurement.
Selection Notes
Select this component when a 3.9V reference is required in a compact SOT-363 footprint. Ensure the circuit design accommodates the 200mW power dissipation limit and the specified thermal operating range. Verify that the dynamic impedance and leakage current specifications meet the precision requirements of the intended voltage regulation or clamping function.
Part Context
This component belongs to the MMBZ5221BTW ~ MMBZ5267BTW series, which covers Zener voltages from 2.4V to 75V. All parts in this series share the same SOT-363 package and 200mW power rating, differing primarily in their nominal voltage and associated impedance values. The series is designed for general-purpose surface mount applications.
Replacement Considerations
Direct replacements must match the SOT-363 package, 200mW power rating, and 3.9V nominal voltage. Verify that substitute components offer equivalent or superior Zener impedance and leakage current specifications to maintain circuit performance.
