1N4750AUR

Overview

The Microchip Technology 1N4750AUR is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device operates in the DO-213AB surface-mount package and dissipates up to 1 W of power. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 35 Ohms, and a test current of 9.5 mA. It supports an operating temperature range from -65°C to +175°C.

Feature Summary

• Provides stable voltage regulation using a single silicon junction structure.
• Engineered for surface-mount installation within compact electronic assemblies.
• Capable of maintaining performance across extended industrial temperature ranges.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronics
• General-purpose voltage regulation in power supplies

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status as indicated by specific suffixes or datasheet revisions. Ensure storage conditions align with moisture sensitivity level requirements prior to assembly. Validate package markings against official documentation to prevent counterfeit infiltration during sourcing.

Selection Notes

Select this component when a 27 V regulation point is required in a surface-mount form factor. Compare thermal dissipation capabilities against circuit load demands. Evaluate impedance characteristics for noise-sensitive designs. Consider lead-free alternatives if environmental regulations mandate specific material restrictions beyond standard specifications.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The 'AUR' suffix typically denotes a specific tape-and-reel packaging configuration for automated surface-mount assembly. It shares core electrical characteristics with axial-lead variants but differs in physical footprint and mounting methodology.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify parametric equivalence with other 27 V, 1 W Zener diodes in the DO-213AB package before substitution.
