JANTX1N4132UR-1

Single Zener Diodes Overview

The JANTX1N4132UR-1 is a Zener voltage regulator diode manufactured by Microchip Technology. It utilizes a DO-213AA surface-mount package and operates within a junction temperature range of -65°C to 175°C. The device provides a nominal Zener voltage of 82V with a power dissipation rating of 0.5W. It features an internal metallurgical bond, indicated by the '-1' suffix, ensuring structural integrity for military applications under MIL-PRF-19500/337 standards.

Single Zener Diodes Feature Summary

• Internal metallurgical bonding for enhanced mechanical stability
• Surface-mount construction in DO-213AA package
• Qualified for military environmental conditions

Single Zener Diodes Applications

• Military electronic systems requiring stable voltage regulation
• High-reliability aerospace circuit protection
• Harsh environment power supply reference circuits

Single Zener Diodes Procurement Notes

Verify the specific revision level and lot traceability documentation upon procurement. Confirm that the received components match the JANTX qualification level required for your design. Ensure storage conditions comply with moisture sensitivity guidelines for leadless surface-mount packages to maintain long-term reliability in critical applications.

Single Zener Diodes Selection Notes

Select this component when a robust 82V regulation point is needed in a compact surface-mount form factor. The internal metallurgical bond distinguishes it from non-bonded equivalents, offering superior resistance to thermal cycling and mechanical shock. Consider the 0.5W power limit and thermal management requirements during PCB layout to ensure safe operation within the specified temperature range.

Single Zener Diodes Part Context

This part belongs to the 1N4099 through 1N4135 series of glass surface mount Zener diodes. The 'JANTX' prefix denotes a specific military quality tier, while the 'UR-1' suffix identifies the round-end surface-mount package with internal metallurgical bonding. This series serves as the SMD equivalent to traditional axial-leaded JEDEC registered Zener diodes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX qualified Zener diodes within the same voltage tolerance class. Verify package compatibility with DO-213AA footprints. Non-metallurgically bonded variants may not meet identical mechanical stress requirements.
