The device has a power dissipation rating of 200mW and operates within a junction temperature range of -55°C to +150°C. It utilizes a SOT-363 plastic package and includes a maximum Zener impedance (ZZT) of 35Ω at an test current of 5.0mA. The component complies with EU RoHS 2.0 standards and uses green molding compound.

Feature Summary

• Planar die construction for automated assembly suitability
• Low profile SOT-363 plastic package
• Lead-free compliance with environmental directives

Applications

• Voltage regulation in portable electronics
• Overvoltage protection circuits
• Reference voltage sources in consumer devices

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm reel quantity and tape specifications. Ensure the component matches the required voltage tolerance and impedance parameters for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 25V Zener reference is needed in a compact SOT-363 footprint. Consider the 200mW power dissipation limit and the 35Ω dynamic impedance at low currents. Verify that the operating temperature range meets the environmental requirements of the end application.

Part Context

This part belongs to the MMBZ5221BTW series, which covers Zener voltages from 2.4V to 75V. All members share identical mechanical dimensions and thermal characteristics, differing only in their electrical voltage and impedance specifications. The series is designed for general-purpose voltage regulation tasks.

Replacement Considerations

Direct replacements must match the SOT-363 package, 200mW power rating, and 25V nominal voltage. Verify pinout compatibility and ensure the substitute component meets the same RoHS and marking code requirements.
