1N5224BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5224BUR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 2.8 V at a test current of 20 mA. It operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W. The device features a maximum dynamic impedance of 30 Ohms, a reverse leakage current of 75 µA at 1 V, and a forward voltage of 1.1 V at 200 mA. It utilizes a DO-213AA (MELF) package with metallurgically bonded end caps.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance levels and RoHS compliance status. Ensure that the tape and reel packaging aligns with automated assembly requirements. Confirm that the ordering information matches the exact part nomenclature defined by the manufacturer for the intended reliability level.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. The metallurgically bonded construction provides robustness against mechanical stress. Consider the low capacitance characteristics for signal integrity in sensitive environments requiring stable voltage references.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount counterpart to the traditional axial-leaded 1N5221 through 1N5281 series. The series covers a wide voltage range from 2.4 V to 200 V, offering various tolerance options including 1%, 2%, 5%, and 10% configurations.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA (MLL34/SOD80) MELF Zener diodes with matching 2.8 V specifications. Verify thermal resistance and power derating curves match the original design constraints before substitution.
