MMBZ5223BW-7

Single Zener Diodes Overview

The MMBZ5223BW-7 is a single silicon unidirectional Zener diode from Diodes Incorporated, housed in an SOT-323 surface-mount package. It provides a nominal Zener voltage of 2.7 V with a tolerance range of 2.57 V to 2.84 V at a test current of 0.25 mA. The device supports a maximum power dissipation of 200 mW and operates within a temperature range of -65 °C to +150 °C. Key electrical characteristics include a maximum Zener impedance of 30 Ω and a maximum reverse leakage current of 75 µA at 1.0 V.

Single Zener Diodes Feature Summary

• Small surface-mount package ideally suited for automated assembly processes
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free "Green" device utilizing molded plastic compound
• Qualified to AEC-Q101 standards for high reliability applications

Single Zener Diodes Applications

• Voltage regulation in compact electronic circuits

• Reference voltage generation in low-power systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component version utilizes the green molding compound if halogen-free compliance is mandatory for the project. Ensure the procurement channel is authorized to guarantee product authenticity and traceability according to manufacturer guidelines.

Single Zener Diodes Selection Notes

Select this component when a precise 2.7 V reference is required in a minimal footprint. The SOT-323 case size offers space efficiency compared to larger packages. Consider the thermal resistance and derating requirements if operating near the upper temperature limits or under continuous load conditions.

Single Zener Diodes Part Context

This part belongs to the MMBZ5221BW through MMBZ5259BW series of 200 mW surface mount Zener diodes. The series covers a wide voltage range from 2.4 V to 39 V, all sharing the same SOT-323 mechanical outline and general electrical testing conditions defined in datasheet DS31037.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other MMBZ52xxBW variants with different voltage ratings but identical packaging. Cross-referencing requires matching the Zener voltage, power dissipation, and package type.
