JANTXV1N6309C

Single Zener Diodes Overview

The JANTXV1N6309C is a military-qualified Zener voltage regulator manufactured by Microchip Technology. It features a voidless hermetically sealed glass B-SQ MELF package designed for surface mount applications. The device provides a nominal Zener voltage of 2.4 V with a tight tolerance of 2%. It operates within an extended temperature range from -65°C to +175°C and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 100 uA, a Zener impedance of 30 Ohms, and a negative voltage temperature coefficient of -0.085 %/°C.

Single Zener Diodes Feature Summary

• Military-grade reliability through voidless hermetically sealed glass construction
• Surface mount compatibility via the B-SQ MELF package format
• High thermal stability across extreme operating temperatures

Single Zener Diodes Applications

• High-reliability aerospace systems
• Defense electronics requiring failure-intolerant components
• Precision voltage reference circuits in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' against official Microchip documentation to confirm exact tolerance and testing parameters. Ensure procurement channels are authorized to handle military-qualified parts. Confirm RoHS status and compliance requirements prior to ordering. Validate that the B-SQ MELF package dimensions match the target PCB layout constraints.

Single Zener Diodes Selection Notes

Select this component when a low-voltage, high-precision reference is required in a surface mount form factor. The 2% tolerance offers tighter regulation than standard 5% variants. Consider the negative temperature coefficient for thermal compensation design. Verify that the 500 mW power dissipation rating meets the circuit's thermal management capabilities.

Single Zener Diodes Part Context

This part belongs to the industry-recognized 1N6309 series of 0.5 W Zener diodes. It serves as the surface mount equivalent of axial leaded versions. The JANTXV qualification level indicates enhanced screening beyond standard JAN specifications. It is suitable for applications where space constraints preclude through-hole mounting.
