1N4569/TR

Single Zener Diodes Overview

The Microchip Technology 1N4569/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.0005%/°C. It operates at a test current of 0.5 mA, providing minimal voltage change over a broad operating temperature range from -55°C to +100°C. The device features a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package and includes an internal metallurgical bond. The 'TR' suffix indicates availability in tape and reel packaging per EIA-296 standards.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage drift across wide temperature ranges
• Internal metallurgical bond construction within a hermetically sealed glass case
• Flexible axial-leaded terminals compatible with standard through-hole mounting

Single Zener Diodes Applications

• Precision instrumentation circuits requiring stable voltage references
• Electronic designs demanding low thermal drift performance
• High-reliability military and aerospace systems

Single Zener Diodes Procurement Notes

Verify the specific revision level and manufacturing origin when sourcing this component. Confirm that the 'TR' suffix correctly corresponds to the required tape and reel packaging format for automated assembly processes. Ensure compatibility with MIL-PRF-19500/452 requirements if military qualification is necessary for the application.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with ultra-low temperature coefficients is required. The 0.5 mA test current setting makes it suitable for low-power applications. Consider the DO-7 package dimensions for board layout constraints and verify that the operating temperature range meets the environmental specifications of the target system.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes produced by Microsemi's Scottsdale Division. The series offers various operating currents and temperature coefficients to suit different precision requirements. The 1N4569 specifically targets applications needing the lowest available temperature coefficient within the series.
