1N3822AUR-1

Single Zener Diodes Overview

The Microchip Technology 1N3822AUR-1 is a temperature-compensated Zener diode designed for precision voltage regulation in demanding environments. It features a nominal Zener voltage of 3.6V with a tolerance of ±5% and a maximum power dissipation of 1W. The device utilizes a DO-213AB (MELF) surface-mount package, ensuring robust mechanical stability. It operates reliably across an extended temperature range from -65°C to +175°C, making it suitable for high-reliability applications where standard components may fail due to thermal stress.

Single Zener Diodes Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing PCB footprints for the DO-213AB package. Confirm that the procurement channel provides traceability documentation required for regulated industries. Check for any recent product change notices affecting assembly sites or materials.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required under significant thermal fluctuations. The temperature-compensated characteristic distinguishes it from standard Zener diodes, offering improved stability without external compensation networks. Consider the 1W power rating and MELF package size for space-constrained designs requiring high thermal endurance.
