JANTX1N5538C-1/TR

Single Zener Diodes Overview

The JANTX1N5538C-1/TR is a military-grade Zener diode manufactured by Microchip Technology. It features an 18V nominal Zener voltage with a tight 2% tolerance, tested at 1mA current. The device operates in the DO-35 axial leaded package and dissipates up to 500mW of power. It supports a wide temperature range from -65°C to +175°C and exhibits low reverse leakage current of 10nA maximum.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with 2% tolerance for high-reliability applications
• Engineered for extreme environments with operation up to 175°C
• Utilizes hermetically sealed glass construction for radiation hardness

Single Zener Diodes Applications

• Military avionics systems requiring strict voltage stability
• Spacecraft power supply regulation circuits
• High-reliability industrial control equipment

Single Zener Diodes Procurement Notes

Verify the specific JAN prefix and suffix configuration against the original design specification sheet. Confirm that the JANTX qualification level meets the project's radiation and reliability requirements. Ensure the DO-35 package dimensions are compatible with the existing PCB footprint before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 18V reference is required under harsh environmental conditions. The JANTX designation indicates enhanced screening compared to standard commercial parts. Consider the thermal management capabilities of the DO-35 package if operating near the maximum power dissipation limit.

Single Zener Diodes Part Context

This part belongs to the 1N5538 series of low-power Zener diodes. The JANTX variant represents a screened military grade offering improved consistency over standard commercial equivalents. It serves as a critical component in precision analog circuits where voltage drift must be minimized across wide temperature spans.
