1N5530DUR-1/TR

Overview

The Microchip Technology 1N5530DUR-1/TR is a single Zener diode designed for surface-mount applications. It features a nominal Zener voltage of 10 V with a tight tolerance of ±1%. The device operates at a test current of 1 mA and exhibits a maximum reverse leakage current of 50 nA. It has a power dissipation rating of 500 mW and a Zener impedance of 60 ohms. The component is housed in a DO-213AA (SMB) package and is supplied in tape and reel packaging.

Feature Summary

• High precision voltage regulation with ±1% tolerance
• Low leakage current characteristics
• Surface-mount compatible construction

Applications

• Precision voltage reference circuits
• Voltage regulator designs
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm exact manufacturing lot attributes and compliance status. Ensure the DO-213AA package dimensions match the target PCB footprint. Confirm that the 1 mA test current aligns with the circuit design requirements for accurate voltage regulation.

Selection Notes

Select this component when high accuracy is required due to the 1% voltage tolerance. The low 50 nA leakage current makes it suitable for sensitive analog interfaces. The 500 mW power rating supports moderate current handling in compact surface-mount layouts compared to through-hole alternatives.
