1N4126UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4126UR/TR is a surface-mount Zener diode housed in the DO-213AA (SOD-80) package. It features a nominal Zener voltage of 51V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and a reverse leakage current of 10 nA. It is supplied in tape and reel packaging for automated assembly processes.

Single Zener Diodes Feature Summary

• Surface-mount construction in a compact DO-213AA package
• Precision voltage regulation at 51V with tight tolerance
• Low leakage current characteristics

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm the DO-213AA footprint compatibility with your PCB design. Ensure the 51V rating meets your circuit requirements. Check for any RoHS compliance documentation if required by your manufacturing standards. Validate the manufacturer part number against official Microchip databases before purchase.

Single Zener Diodes Selection Notes

Select this component when a precise 51V reference is needed in a small surface-mount form factor. The 500 mW power rating suits low-current regulation tasks. Consider the ±5% tolerance for general-purpose applications where high precision is not critical. The SOD-80 package offers space efficiency compared to through-hole alternatives.

Single Zener Diodes Part Context

This part belongs to Microchip's single Zener diode lineup, designed for voltage regulation and protection. The 1N4126 series provides stable breakdown voltages for various electronic circuits. The UR suffix typically denotes the specific package style and termination type within the product family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 51V Zener diodes in the SOD-80 package from different manufacturers, provided they meet the 500 mW power and ±5% tolerance specifications. Verify pinout and thermal characteristics before substitution.
