1N4567E3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4567E3/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 is housed in a DO-7 (DO-204AA) glass axial package.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bonding within hermetically sealed glass case
• ESD non-sensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Precision circuit designs demanding low temperature drift
• Military qualification applications via JAN/JANTX prefixes

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the required military or commercial qualification level, as prefixes alter the component's certification rather than its electrical function.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.002 %/°C temperature coefficient is required. Confirm that the 0.5 mA test current aligns with the target circuit design to maintain optimal voltage-temperature stability and ensure the DO-7 package fits the mechanical constraints.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of zero-TC reference diodes manufactured by Microsemi/Microchip Technology. The series provides various temperature coefficients and test currents while maintaining a consistent 6.4 V nominal voltage across all variants.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 6.4 V temperature-compensated Zener diodes from manufacturers such as ON Semiconductor or Texas Instruments, provided they meet the 0.002 %/°C coefficient and 0.5 mA test current specifications.
