1N3827AUR-1

Single Zener Diodes Overview

The 1N3827AUR-1 is a military-grade Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AB (MELF) glass package. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5% and a maximum power dissipation of 1 W. The device operates within an extended temperature range of -65°C to +175°C and complies with MIL-PRF-19500/115 standards. Key electrical characteristics include a maximum Zener impedance of 5 Ohms at a test current of 45 mA, a reverse leakage current of 3 µA at 2 V, and a forward voltage drop of 1.2 V at 200 mA.

Single Zener Diodes Feature Summary

• Aviation instrumentation circuits
• Defense communication equipment

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging configuration, such as bulk or tape and reel, as these affect handling procedures. Confirm compliance with specific military quality levels like JAN or JANTX if mandated by the design specification. Ensure the component source is traceable to authorized manufacturers to guarantee authenticity and adherence to MIL-PRF-19500/115 standards.

Single Zener Diodes Selection Notes

Select this component when a robust, leadless surface-mount Zener diode is required for harsh environments. The DO-213AB package offers mechanical stability suitable for automated assembly processes. Consider the 1 W power rating and wide thermal operating range when designing for high-temperature military or aerospace applications where standard commercial components may fail.

Single Zener Diodes Part Context

This part belongs to the 1N3821AUR-1 through 1N3828AUR-1 series, which provides a range of Zener voltages from 3.3 V to 75 V in the same MELF package. The series is available in various military qualification grades, including JAN, JANTX, and JANTXV, allowing designers to balance performance requirements with cost constraints while maintaining consistent physical footprint and mounting characteristics.

Single Zener Diodes Replacement Considerations

Direct equivalents are available within the same series, such as JAN1N3827AUR-1 or JANTX1N3827AUR-1, which share identical electrical parameters but differ in military qualification levels. Cross-brand replacements require careful verification of pinout compatibility, thermal resistance, and voltage tolerance to ensure circuit integrity without redesign.
