JANTX1N6331US

Single Zener Diodes Overview

The JANTX1N6331US is a military-qualified Zener voltage regulator diode manufactured by Microchip Technology. It features a B-SQ MELF surface-mount package with voidless hermetically sealed glass construction and internal metallurgical bonds. The device provides a nominal Zener voltage of 20V with a 5% tolerance at a test current of 6.2mA. Key electrical parameters include a maximum reverse leakage current of 50nA, a Zener impedance of 18 Ohms, and a power dissipation rating of 500mW. It operates within a temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Military-grade reliability with voidless hermetically sealed glass construction
• Internal Category I metallurgical bonds for enhanced durability
• Surface-mount equivalent of the JEDEC registered 1N6309 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 that the specific part number suffix matches the required qualification level and packaging format. Confirm compliance with MIL-PRF-19500/533 standards. Ensure the supplier provides appropriate documentation for military-grade components. Check for availability constraints as these parts may have limited stock or long production cycles.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for applications traditionally using axial leaded 1N6331 diodes. The B-SQ MELF package offers space savings while maintaining hermetic sealing. Consider the 5% voltage tolerance and 500mW power rating against circuit requirements. Verify thermal management capabilities for operation up to 175°C.

Single Zener Diodes Part Context

This device belongs to the 1N6309 through 1N6355 series of Zener voltage regulators. These industry-recognized components are designed for high-reliability environments. The series includes various voltage selections from 2.4V to 200V in standard tolerances. They are available in both through-hole and surface-mount packages to suit different design needs.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JAN1N6331US, JANTXV1N6331US, and commercial equivalents like 1N6331US. Ensure replacement parts match the B-SQ MELF package dimensions and hermetic sealing requirements. Verify that alternative manufacturers meet the same military qualification standards if required.
