1N4762UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4762UR-1 is a single silicon Zener diode designed for voltage regulation applications. It features an 82V nominal Zener voltage with a tolerance of ±10% and a maximum power dissipation of 1W. The device utilizes a DO-213AB (MELF) surface-mount package, constructed with hermetically sealed glass encapsulation. It operates within a temperature range of -65°C to +175°C and is classified as unidirectional.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF construction for high reliability
• Surface-mount DO-213AB package design
• High operating temperature capability up to 175°C

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection systems
• Clamping applications in electronic assemblies

Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 indicates the standard surface-mount variant. Confirm RoHS compliance status as leaded components may be restricted in certain jurisdictions. Ensure the supplier provides official Microchip documentation to validate the hermetic seal integrity and electrical parameters against the datasheet specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a ruggedized, surface-mount Zener diode is required for harsh environments. The DO-213AB package offers space efficiency compared to axial leads. Consider the 1W power rating and 82V breakdown voltage to ensure compatibility with the target circuit's voltage and thermal requirements.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The 'UR' designation typically denotes the surface-mount MELF configuration, distinguishing it from axial leaded variants like the 1N4762G or plastic packaged versions. It serves as a robust alternative for military and industrial applications requiring high reliability.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4762A devices in DO-213AB packages. Verify that replacement parts match the 82V Zener voltage, 1W power rating, and hermetic sealing requirements to maintain circuit performance and environmental resilience.
