JANTXV1N6351DUS

Single Zener Diodes Overview

The JANTXV1N6351DUS is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It features a surface-mount B-SQ MELF package with voidless hermetically sealed glass construction and internal metallurgical bonds. The device provides a nominal Zener voltage of 130 V with a 5% tolerance at a test current of 0.95 mA. It has a power dissipation rating of 500 mW, a maximum reverse leakage current of 2 µA, and an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Military qualification per MIL-PRF-19500/533 for high-reliability applications
• Voidless hermetically sealed glass package with internal metallurgical bonds
• Surface-mount equivalent of the JEDEC registered 1N6309 through 1N6355 series

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military electronic circuits
• Critical voltage regulation where failure is not tolerated

Single Zener Diodes Procurement Notes

Verify the specific suffix DUS against official Microchip documentation to confirm package type and testing requirements. Ensure procurement channels are authorized to guarantee authenticity for military-grade components. Confirm that the JANTXV grade meets the specific reliability standards required for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for high-voltage regulation in harsh environments. The 130 V rating suits applications needing precise reference voltages above standard low-voltage options. The hermetic seal ensures long-term stability compared to non-sealed commercial alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N63xx series of 500 mW Zener diodes offered by Microchip. The series includes axial leaded and surface-mount variants covering voltages from 2.4 V to 200 V. The JANTXV designation indicates enhanced screening beyond standard JAN levels, targeting defense and space sectors.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTXV1N6351 variants with different packaging such as JANTXV1N6351US (axial) if form factor changes are acceptable. Verify electrical parameters match exactly before substitution.
