1N4754AUR

Overview

The Microchip Technology 1N4754AUR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 39 V with a tolerance of ±5%. The device operates in the DO-213AB (MELF) surface-mount package and supports a maximum power dissipation of 1 W. It maintains functionality across an extended temperature range from -65°C to +175°C, ensuring reliability in demanding environments.

Feature Summary

• Provides stable voltage regulation using planar Zener technology
• Supports high-temperature operation up to 175°C junction temperature
• Utilizes glass-passivated die for enhanced environmental stability

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications within signal processing paths

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and specific manufacturing lot details prior to integration. Ensure storage conditions align with manufacturer guidelines to maintain device integrity during handling and assembly processes.

Selection Notes

Select this component when a 39 V regulation point is required in a compact surface-mount form factor. Consider the 1 W power rating and wide thermal operating range for suitability in space-constrained designs. Verify that the DO-213AB footprint matches the target PCB layout constraints.

Part Context

This part belongs to the standard 1N47xx series of Zener diodes manufactured by Microchip Technology. The 'AUR' suffix typically denotes specific packaging or tape-and-reel configurations within the MELF family. These devices are engineered for general-purpose regulation tasks where consistent performance across varying temperatures is critical.

Replacement Considerations

The 1N4754AUR/TR is listed as a parameter-equivalent substitute by distributors.
