JANTX1N4115UR-1/TR

Single Zener Diodes Overview

The JANTX1N4115UR-1/TR is a Zener voltage regulator manufactured by Microchip Technology. It features a 22V nominal Zener voltage with a 5% tolerance and a dynamic impedance of 150 Ohms. The device utilizes a DO-213AA-2 surface-mount package, equivalent to the axial 1N4115 series. It incorporates an internal metallurgical bond for enhanced reliability in harsh environments. The component operates within a temperature range of -65°C to +175°C and supports a maximum power dissipation of 500mW.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for improved structural integrity
• JANTX military qualification level for high-reliability applications
• Surface-mount DO-213AA-2 package design

Single Zener Diodes Applications

• Military electronic systems requiring ruggedized components
• Aerospace voltage regulation circuits
• High-reliability industrial control equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure the correct metallurgical bond and packaging variant. Confirm that the JANTX grade meets the required environmental testing standards for the target application. Cross-reference the manufacturer's current lifecycle status to avoid obsolescence risks during production.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for a standard 22V Zener function in demanding environments. The internal metallurgical bond distinguishes it from non-bonded equivalents, offering superior resistance to mechanical shock. Ensure the PCB layout accommodates the DO-213AA-2 footprint and thermal requirements for 500mW dissipation.

Single Zener Diodes Part Context

This part belongs to the Microsemi/Microchip family of glass surface-mount Zener diodes. It serves as the surface-mount equivalent to the JEDEC-registered 1N4099 through 1N4135 axial series. The 'UR-1' designation specifically indicates the inclusion of an internal metallurgical bond, while 'JANTX' denotes the military quality tier.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX qualified Zener diodes with identical 22V ratings and DO-213AA-2 packages. Verify compatibility with non-bonded variants if mechanical stress is not a primary concern.
