Overview
The MMBZ5229BTW_R1_00001 is a surface mount silicon zener diode from the Panjit MMBZ5221BTW series. It features planar die construction and operates within a junction temperature range of -55°C to +150°C. The device provides a nominal zener voltage of 4.3V with a tolerance of ±5% (4.09V to 4.52V). Maximum power dissipation is rated at 200mW, and peak forward surge current is 2A. Electrical characteristics include a maximum zener impedance of 22Ω at Izt=20mA and a maximum reverse leakage current of 5µA at Vr=1.0V. The component is housed in an SOT-363 plastic package.
Feature Summary
- Planar die construction for reliable performance
- Compliant with EU RoHS 2.0 standards
- Utilizes green molding compound per IEC 61249 standard
Applications
- Automated assembly processes
- Voltage regulation circuits
- General purpose electronic applications
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and marking codes. Confirm that the SOT-363 package dimensions align with the target PCB footprint layout. Ensure compliance with environmental directives such as RoHS 2.0 and IEC 61249 requirements before finalizing procurement specifications.
Selection Notes
Select this component when a 4.3V reference or regulation point is required in a compact surface mount design. Verify that the 200mW power dissipation rating meets the thermal requirements of the application. Consider the SOT-363 package size constraints and the specified operating temperature range of -55°C to +150°C during circuit design.
Part Context
This part belongs to the MMBZ5221BTW ~ MMBZ5267BTW series, which covers zener voltages from 2.4V to 75V. All members share identical mechanical and electrical structural characteristics, differing primarily in their nominal breakdown voltage and associated impedance values. The series is designed for high-volume automated manufacturing.
Replacement Considerations
Direct substitutes must match the 4.3V nominal voltage, 200mW power rating, and SOT-363 package. Verify that alternative components meet the same maximum zener impedance and leakage current specifications to maintain circuit performance equivalence.
