JANTX1N986C-1/TR

Single Zener Diodes Overview

The JANTX1N986C-1/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 110 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and operates within an extended temperature range of -55°C to +175°C. It utilizes the DO-204AH (DO-35) axial through-hole package. Key electrical characteristics include a reverse leakage current of 500 nA at 84 V and a Zener impedance of 750 Ohms.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% tolerance on the 110 V Zener voltage.
• Engineered for high-temperature reliability with an operational range extending to +175°C.
• Constructed in a rugged DO-204AH axial leaded package suitable for through-hole mounting.

Single Zener Diodes Applications

• Military aerospace voltage reference circuits
• High-reliability industrial power supply regulation
• Avionics protection and clamping applications

Single Zener Diodes Procurement Notes

Verify that the specific suffix /TR indicates tape-and-reel packaging if reel handling is required for assembly. Confirm RoHS compliance status as military-grade variants often differ from commercial standards. Ensure the supplier provides traceability documentation consistent with JAN specifications. Validate that the component matches the exact 110 V rating and 500 mW power dissipation limits for the target design.

Single Zener Diodes Selection Notes

Select this component when a stable 110 V reference is required under extreme thermal conditions. The ±2% tolerance offers higher precision than standard commercial equivalents. Consider the DO-204AH package size constraints for PCB layout. Evaluate the 750 Ohm impedance for noise sensitivity in sensitive analog front ends. Ensure the 500 mW power rating accommodates the expected current load without exceeding thermal limits.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JAN designation signifies qualification for military and aerospace environments. The TX suffix typically denotes enhanced screening or testing levels compared to standard JAN parts. This series is distinct from lower-power or surface-mount alternatives in the same product family.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 110 V Zener voltage, ±2% tolerance, and 500 mW power rating. Verify that any replacement supports the -55°C to +175°C operating temperature range. Ensure the alternative uses the DO-204AH axial package for mechanical compatibility. Check if the substitute meets the same military reliability standards if applicable.
