JANTX1N967D-1

Single Zener Diodes Overview

The JANTX1N967D-1 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation in through-hole applications. It features an 18 V nominal Zener voltage with a 5% tolerance and operates within a wide temperature range of -65°C to +175°C. The device dissipates up to 500 mW of power and exhibits a Zener impedance of 21 Ohms at a test current of 7 mA. Packaged in a DO-35-2 axial leaded format, it maintains a maximum reverse leakage current of 500 nA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single Zener junction configuration.
• Engineered for high-temperature reliability suitable for extreme environments.
• Utilizes a robust axial leaded package for secure through-hole mounting.

Single Zener Diodes Applications

• Military electronic systems requiring radiation-hardened or high-reliability components
• Aviation avionics circuits demanding extended operational temperature ranges
• Spacecraft power management and voltage reference modules

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variations such as /TR indicate tape-and-reel packaging which differs from standard bulk supply. Confirm that the procurement channel sources directly from authorized distributors to ensure component authenticity and traceability. Check for RoHS compliance status, as military-grade variants often carry non-compliant markings due to material composition requirements.

Single Zener Diodes Selection Notes

Select this component when a precise 18 V reference is required in harsh thermal conditions. The DO-35 package suits designs needing manual assembly or rework capabilities. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specific 21 Ohm impedance characteristics for accurate noise performance.

Single Zener Diodes Part Context

This part belongs to the 1N967 series of Zener diodes produced under MIL-PRF-19500/117 specifications. The 'JANTX' prefix denotes a specific quality level within Microchip's military product line, distinguishing it from commercial equivalents. It serves as a ruggedized alternative for critical infrastructure where standard industrial parts may fail.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic 1N967 equivalents only if military qualification requirements are waived.
