Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and reel specifications. Ensure that the component meets the required environmental compliance standards for the intended application. Cross-reference the part number with the latest datasheet revision to confirm electrical parameters and mechanical dimensions before procurement.
Selection Notes
Select this component based on the required 22V Zener voltage and 200mW power dissipation limits. Consider the SOT-363 package size for space-constrained designs. Verify that the operating temperature range of -55°C to +150°C aligns with the system environment. Check the maximum Zener impedance and leakage current requirements against the circuit design specifications.
Part Context
This part belongs to the MMBZ5221BTW to MMBZ5267BTW series of surface mount silicon Zener diodes manufactured by Panjit International Inc. The series offers various Zener voltages ranging from 2.4V to 75V, all sharing the same 200mW power rating and SOT-363 package form factor. The 'R1' suffix typically indicates a specific tape and reel configuration, while '00001' may denote a specific lot or internal tracking code.
Replacement Considerations
Direct replacements must match the 22V nominal Zener voltage, 200mW power rating, and SOT-363 package. Other manufacturers offering Zener diodes in SOT-363 with similar electrical characteristics can be considered, provided they meet the same thermal and electrical specifications.
