JANTXV1N3828AUR-1

Single Zener Diodes Overview

The JANTXV1N3828AUR-1 is a military-grade Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.2 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range of -65°C to +175°C. It utilizes a leadless DO-213AB (MELF) surface-mount package, ensuring hermetic sealing suitable for harsh environments.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF construction for environmental protection
• Military qualification compliant with MIL-PRF-19500/115 standards
• Extended operating temperature capability up to 175°C
• High precision voltage regulation with ±2% tolerance

Single Zener Diodes Applications

• Precision voltage reference circuits in aerospace systems
• Overvoltage protection in military-grade electronic assemblies
• Voltage clamping in high-reliability industrial control units
• Regulation in extreme environment sensor interfaces

Single Zener Diodes Procurement Notes

Verify the specific suffix 'AUR-1' against the official Microchip datasheet to confirm the exact mechanical dimensions and testing requirements for the MELF variant. Ensure that procurement specifications explicitly require the JANTXV grade to guarantee the ±2% tolerance and hermetic seal characteristics defined in the military standard documentation.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode requires both high thermal stability and strict voltage accuracy in confined spaces. The DO-213AB package offers a compact footprint compared to axial leads while maintaining robust performance. Consider the 1W power rating and wide temperature range to ensure compatibility with high-density circuit designs subjected to thermal stress.

Single Zener Diodes Part Context

This part belongs to the 1N3828 series of silicon voltage regulators produced under MIL-PRF-19500/115. The JANTXV designation indicates enhanced screening and reliability testing beyond the standard JAN grade. The UR-1 suffix specifically denotes the leadless MELF package style, distinguishing it from the axial-leaded DO-41 variants available in the same electrical family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' MIL-PRF-19500/115 qualified 1N3828A devices in the DO-213AB package. Verify that any replacement maintains the 6.2 V nominal voltage, ±2% tolerance, and 1 W power rating. Ensure the substitute also meets the -65°C to +175°C operating temperature range and hermetic sealing requirements.
