JANTXV1N5419

Single Diodes Overview

The JANTXV1N5419 is a general-purpose rectifier diode manufactured by Microchip Technology. It features a maximum repetitive reverse voltage of 500 V and an average forward rectified current of 3 A. The device utilizes a B-Package-2 axial leaded configuration suitable for through-hole mounting. Key electrical characteristics include a maximum forward voltage of 1.5 V at rated current, a peak non-repetitive surge current capability of 80 A, and a low reverse leakage current of 1 µA. The component is designed to operate within a junction temperature range from -65 °C to +175 °C, ensuring reliability in demanding environments.

Single Diodes Feature Summary

• High-temperature operation capability up to 175 °C
• Rad-hardened construction for radiation tolerance
• Fast recovery performance with low leakage current

Single Diodes Applications

• Military aerospace power supplies
• Spacecraft electronic systems
• Harsh environment rectification circuits

Single Diodes Procurement Notes

Verify the specific suffix 'TXV' indicates enhanced testing levels compared to standard variants. Confirm that the B-package form factor matches the target PCB layout requirements. Ensure procurement channels provide traceability documentation required for defense or space applications. Check for RoHS exemptions as military-grade components often fall outside standard compliance scopes.

Single Diodes Selection Notes

Select this component when high thermal stability and radiation hardness are critical design constraints. The 500 V rating provides sufficient margin for standard industrial AC line voltages. Consider the 3 A continuous current limit against peak load demands. The axial package requires specific board spacing compared to surface-mount alternatives.

Single Diodes Part Context

This part belongs to the JANS/JANTXV series of rad-hardened discrete semiconductors produced by Microchip. These devices are qualified for use in satellite and missile guidance systems where standard commercial parts would fail due to ionizing radiation effects. The 1N54xx family represents a legacy standard adapted for high-reliability specifications.

Single Diodes Replacement Considerations

Direct replacements must match the JANTXV qualification level. Standard 1N5419 diodes lack the necessary radiation hardness and extended temperature range. Verify pinout compatibility with the existing B-package footprint before substitution.
