1N4569A-1E3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4569A-1E3/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, features an internal metallurgical bond, and is housed in a DO-7 (DO-204AA) glass axial-leaded package. The device supports tape-and-reel packaging via the TR suffix and complies with JEDEC registration standards for the 1N4565 through 1N4584A series.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range
• Features internal metallurgical bonding for structural integrity
• Offers flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift
• Precision analog signal processing applications

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the required military qualification prefixes if applicable, as standard commercial versions lack these ratings. Confirm the presence of the TR suffix indicates tape-and-reel packaging rather than bulk. Ensure the ordering suffix matches the desired tolerance level, as tighter tolerances require additional hyphenated identifiers beyond the base model number.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with ultra-low temperature drift is required. The 0.5 mA test current option suits low-power applications where self-heating must be minimized. Consider the DO-7 package for through-hole implementations requiring hermetic sealing. Evaluate alternative series members if different test currents or slightly higher temperature coefficients are acceptable for cost optimization.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A series of Zero-TC Reference Diodes manufactured by Microsemi, now part of Microchip Technology. The series provides various operating currents and temperature coefficients centered around the 6.4 V nominal voltage. These diodes are designed for high-stability applications and are available in multiple package styles including DO-7 and surface mount equivalents.
