1N4567A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4567A/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.002 %/°C. It operates at a test current of 0.5 mA, features a maximum reverse leakage current of 2 µA at 3 V, and has a dynamic impedance of 200 Ω. The device dissipates 500 mW and functions within a temperature range of -55°C to +100°C. Packaged in a hermetically sealed DO-7 (DO-204AA) glass axial leaded case, the TR suffix indicates tape and reel packaging.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet identifies Microsemi Scottsdale Division while the brand is listed as Microchip Technology. Confirm that the TR suffix correctly denotes tape and reel packaging per EIA-296 standards. Ensure the component meets the required environmental specifications for the intended operating temperature range.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a tight temperature coefficient of 0.002 %/°C is required. The 0.5 mA test current makes it suitable for low-power applications. Consider military variants like JANTX1N4567A-1 if radiation hardening or enhanced reliability is necessary for the deployment environment.
