Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and marking codes. Confirm that the component meets all required environmental standards, such as RoHS 2.0 compliance, before finalizing procurement orders. Cross-reference the part number with the latest datasheet revisions to avoid discrepancies in electrical parameters or mechanical dimensions.
Selection Notes
Select this component based on the required 2.5V Zener voltage and 200mW power dissipation limits. Ensure the application circuit accounts for the specified maximum Zener impedance of 20Ω and reverse leakage current of 1.0μA. Verify that the operating temperature range of -55°C to +150°C aligns with the system's thermal environment requirements.
Part Context
This part belongs to the MMBZ5221BTW ~ MMBZ5267BTW series of surface mount silicon Zener diodes manufactured by Panjit International Inc. The series covers a wide voltage range from 2.4V to 75V, all sharing the same SOT-363 package and 200mW power rating. The 'R1' suffix typically indicates reel packaging, consistent with the series' standard packing information.
Replacement Considerations
Direct replacements must match the 2.5V nominal Zener voltage, 200mW power rating, and SOT-363 package. Verify equivalent electrical parameters, including Zener impedance and leakage current, to ensure circuit compatibility. Check for identical mechanical dimensions and marking codes if board space or identification is critical.
