Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the requested part number matches the exact electrical specifications required for the design. Ensure compliance with environmental directives relevant to the target market before finalizing procurement orders.
Selection Notes
Select this component when a compact SOT-363 footprint is required for 18V regulation. Consider the 200mW power dissipation limit and thermal derating curves for high-temperature environments. Verify that the 21Ω dynamic impedance meets the noise and stability requirements of the application circuit.
Part Context
This part belongs to the MMBZ5221BTW through MMBZ5267BTW series of surface mount silicon Zener diodes manufactured by Panjit International Inc. The series covers a voltage range from 2.4V to 75V, all utilizing the same SOT-363 package and planar die technology for consistent manufacturing quality.
Replacement Considerations
Direct substitutes within the same series include other MMBZ52xxBTW variants if voltage requirements differ. Cross-brand replacements must match the SOT-363 package, 200mW power rating, and 18V nominal voltage with compatible impedance and leakage specifications.
