1N4684UR-1/TR

Overview

The Microchip Technology 1N4684UR-1/TR is a hermetically sealed silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.3 V with a tolerance of 5% and a power dissipation rating of 0.5 W. The component utilizes a MELF-2 (DO-213AA) surface-mount package and supports a maximum reverse current of 7.5 uA. It operates within an extended temperature range from -65 C to +175 C, ensuring reliability in demanding environments.

Feature Summary

Hermetically sealed glass construction for environmental protection
Extended high-temperature operational capability up to 175 C
Surface-mount MELF-2 package design

Applications

Military aerospace systems
High-reliability industrial electronics
Harsh environment voltage regulation

Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm the inclusion of hermetic sealing and reel packaging specifications. Ensure that the DO-213AA footprint requirements align with the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when hermetic sealing and high-temperature stability are required for a 3.3 V reference. The MELF-2 package offers a compact solution suitable for automated assembly processes while maintaining robust performance under extreme thermal conditions compared to standard plastic packages.

Part Context

This part belongs to the 1N4684 series of Zener diodes manufactured by Microchip Technology. It serves as a specialized variant offering hermetic sealing and surface-mount capabilities, distinguishing it from through-hole equivalents within the broader voltage regulator product line.

Replacement Considerations

Consult official substitution guides for compatible hermetic Zener diodes. Verify pinout compatibility and thermal characteristics when evaluating alternative suppliers or updated revisions.
