JANTXV1N6319DUS/TR

Single Zener Diodes Overview

The JANTXV1N6319DUS/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a B-SQ-MELF-2 package and operates within an extended temperature range from -65°C to +175°C. The device provides a nominal Zener voltage of 6.2 V with a tight tolerance of 1% at a test current of 20 mA. It dissipates up to 500 mW of power and exhibits a low Zener impedance of 3 Ohms. Maximum reverse leakage current is specified at 2 uA, ensuring minimal standby losses in regulated circuits.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with 1% tolerance for high-accuracy reference applications
• Engineered for extreme environments with operation up to +175°C
• Utilizes a compact square MELF surface-mount package for automated assembly

Single Zener Diodes Applications

• Precision voltage reference circuits requiring tight tolerance
• Over-voltage protection in harsh industrial or aerospace systems

Single Zener Diodes Procurement Notes

Verify the specific suffix DUS/TR against official Microchip documentation to confirm tape-and-reel packaging and exact electrical limits. Ensure compatibility with the B-SQ-MELF-2 footprint during PCB layout. Confirm RoHS status and military qualification requirements directly with the manufacturer prior to ordering.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and high-temperature stability are required in a small form factor. Compare the 1% tolerance and 3 Ohm impedance against standard commercial alternatives to ensure performance meets circuit specifications. Verify that the 500 mW power dissipation rating aligns with thermal management capabilities in the final enclosure design.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of radiation-hardened and high-reliability Zener diodes produced by Microchip. These components are typically utilized in defense, aerospace, and critical infrastructure sectors where standard commercial parts may fail under stress. The JANTXV designation indicates enhanced screening and quality control compared to baseline military grades.

Single Zener Diodes Replacement Considerations

Consult Microchip datasheets for direct equivalents within the 1N6319 family. Verify pinout compatibility and package dimensions before substituting with other manufacturers' MELF devices. Ensure replacement parts meet the same -65°C to +175°C operating range and 1% voltage tolerance requirements.
