MMBZ5255BTW_R1_00001

Overview

The MMBZ5255BTW_R1_00001 is a surface mount silicon Zener diode from the Panjit MMBZ5221BTW series. It features a nominal Zener voltage of 28V with a tolerance range of 26.60V to 29.40V. The device operates within a power dissipation limit of 200mW and utilizes an SOT-363 plastic package. Electrical characteristics include a maximum Zener impedance (ZZT) of 44Ω at IZT=4.5mA, and a maximum reverse leakage current of 0.1μA at VR=21V. The component supports an operating junction temperature range of -55°C to +150°C.

Feature Summary

Planar die construction for automated assembly suitability
Compliance with EU RoHS 2.0 directives
Green molding compound per IEC 61249 standard

Applications

Voltage regulation in portable electronics
Protection circuits in handheld devices
Reference voltage sources in instrumentation

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. Ensure the requested part number matches the exact electrical specifications required for the design. Confirm compliance requirements such as RoHS status prior to procurement.

Selection Notes

Select this component based on the required 28V Zener voltage and 200mW power rating. Consider the SOT-363 package dimensions for board space constraints. Evaluate the dynamic impedance and leakage current specifications against circuit sensitivity requirements.

Part Context

This component belongs to the MMBZ5221BTW ~ MMBZ5267BTW series of surface mount silicon Zener diodes manufactured by Panjit International Inc. The series covers a voltage range from 2.4V to 75V, offering various voltage options in the compact SOT-363 package format.

Replacement Considerations

Direct replacements within the same series include other MMBZ52xxBTW variants with different voltage ratings. Cross-referencing with other manufacturers' SOT-363 Zener diodes requires verifying matching voltage, power dissipation, and impedance parameters.
