JANTXV1N6320D

Single Zener Diodes Overview

The JANTXV1N6320D is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tight tolerance of 1%. The device operates in the SMD/SMT configuration within a B-SQ-MELF-2 package and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 2 uA, a Zener impedance of 3 Ohms, and a test current of 20 mA. It supports a forward current of 1 A and maintains functionality across an extended temperature range from -65 C to +175 C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with 1% tolerance for high-stability reference circuits.
• Engineered for extreme environmental reliability with operation up to +175 C.
• Utilizes a compact MELF surface-mount package for automated assembly integration.

Single Zener Diodes Applications

• Precision voltage reference generation in aerospace systems
• Overvoltage protection in military-grade electronic circuits
• Voltage clamping in harsh environment signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific suffix D against official Microchip documentation to confirm exact binning or testing standards. Ensure compatibility with B-SQ-MELF-2 footprint requirements during PCB layout. Confirm RoHS status and lead times directly with authorized distributors as supply chain conditions vary. Validate that the 1% tolerance meets the strictest design constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 6.8 V reference is required in space-constrained surface-mount designs. The low Zener impedance of 3 Ohms makes it suitable for applications demanding minimal voltage variation under load changes. Consider the wide thermal operating range if the deployment environment exceeds standard industrial limits. Compare against through-hole alternatives only if mechanical mounting constraints dictate a different package style.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of radiation-hardened and high-reliability Zener diodes produced by Microchip. The series is characterized by stringent quality controls intended for defense and aerospace sectors. The JANTXV designation indicates enhanced screening compared to standard commercial variants, ensuring long-term stability and performance consistency in critical mission-critical applications.

Single Zener Diodes Replacement Considerations

Direct substitutes include JANTXV1N6320US and JANTXV1N6320US/TR, which share identical electrical specifications but may differ in reel packaging or minor suffix variations. Verify pinout and package dimensions match the B-SQ-MELF-2 form factor before substitution.
