1N4569A-1E3

Single Zener Diodes Overview

The 1N4569A-1E3 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 a hermetically sealed glass DO-7 package, and supports an operating temperature range from -55°C to +100°C.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation and other circuit designs requiring a voltage reference
• Temperature coefficient selections available from 0.01%/ºC to 0.0005%/ºC
• Flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Circuit designs demanding minimal voltage change over temperature
• Military qualification applications via JAN/JANTX prefixes

Single Zener Diodes Procurement Notes

Verify the manufacturer origin as Microsemi Scottsdale Division rather than Microchip Technology. Confirm the specific suffix requirements for military qualifications (JAN, JANTX) or tape-and-reel packaging (TR). Ensure the ordering part number matches the required tolerance and temperature coefficient specifications.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with ultra-low temperature drift is required. The 1N4569A-1 variant offers the lowest temperature coefficient in its series. Consider tighter voltage tolerance options by adding percentage suffixes if specified precision is needed beyond standard JEDEC tolerances.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of zero-TC reference diodes. These components are internally metallurgical-bonded and designed for applications requiring high stability. The series includes various operating currents and temperature coefficients to suit different design constraints.

Single Zener Diodes Replacement Considerations

Microsemi also offers military surface mount equivalents in the DO-213AA package by adding the UR-1 suffix and appropriate prefixes, such as JANTX1N4569AUR-1.
