1N4566A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4566A/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.005 %/°C. It operates at a test current of 0.5 mA, features a maximum reverse current of 2 µA at 3 V, and has a dynamic impedance of 200 Ω. The device is housed in a DO-7 (DO-204AA) glass axial-leaded package, supports an operating temperature range of -55°C to +100°C, and dissipates up to 500 mW.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bonding for structural integrity
• Flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' against official documentation to confirm tape-and-reel packaging compliance. Confirm that the manufacturer designation aligns with current corporate records, as historical data may reflect prior entity names. Ensure the component meets all required environmental and military qualification standards specified for the target application before procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a tight temperature coefficient of 0.005 %/°C is required. The 0.5 mA test current option suits low-power applications. Verify that the DO-7 through-hole package fits the board layout and that the -55°C to +100°C operating range covers the environmental conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A series of zero-TC reference diodes. These devices provide a selection of temperature coefficients ranging from 0.01%/°C to 0.0005%/°C. The series includes various operating currents and tolerance options, with some variants available in military qualifications like JAN or JANTX.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include 1N4565A, 1N4567A, and 1N4568A. These parts share the 6.4 V nominal voltage but differ in temperature coefficients and test currents. Verify package compatibility and electrical parameters before substitution.
