1N5227DUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5227DUR-1/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 3.6 V at a test current of 20 mA. It features a maximum dynamic impedance of 24 Ohms and a maximum reverse leakage current of 15 µA. The device operates within a junction temperature range of -65°C to +175°C and dissipates up to 0.5 W. Packaged in a hermetically sealed DO-213AA (MELF) configuration, it offers a tight voltage tolerance of ±1%.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass surface mount package
• Tight voltage tolerance of ±1%
• Inherently radiation hard design

Single Zener Diodes Applications

• ESD protection circuits
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against official manufacturer documentation to confirm RoHS compliance status and exact screening levels. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the selected variant meets all necessary environmental and reliability standards for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is required in a compact surface mount form factor. The ±1% tolerance makes it suitable for applications demanding high accuracy. Consider the low capacitance characteristics for signal integrity. Verify thermal derating curves if operating near maximum power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which provides surface mount equivalents to the traditional axial-leaded JEDEC registered 1N5221 to 1N5281 series. The series covers Zener voltages from 2.4 V to 200 V in a metallurgically bonded glass package designed for robust performance.

Single Zener Diodes Replacement Considerations

Direct replacements include other variants within the 1N5221BUR-1 thru 1N5281BUR-1 series or standard axial-leaded equivalents like the 1N5227B-1, provided package compatibility and tolerance specifications are verified.
