1N4565A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4565A-1/TR is a temperature compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.01 %/°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 with internal metallurgical bonding and is supplied in tape and reel packaging.

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
• Features an internal metallurgical bond construction within a hermetically sealed glass case
• Complies with MIL-STD-750 Method 1020 regarding electrostatic discharge sensitivity

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Precision analog circuit designs demanding low temperature drift
• Military qualification applications under JAN, JANTX, or JANTXV standards

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for military qualifications when ordering. Confirm that the tape and reel packaging aligns with automated assembly equipment specifications. Ensure the selected part number includes the necessary tolerance designation if tighter voltage accuracy than standard is required for the design.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.01 %/°C temperature coefficient is required. Consider the 0.5 mA test current for power dissipation limits. Evaluate the DO-7 package dimensions against board space constraints. Verify compatibility with MIL-PRF-19500/452 standards if military grade reliability is mandated.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microsemi Scottsdale Division. The series offers various temperature coefficients and operating currents while maintaining a consistent 6.4 V nominal voltage across all variants.

Single Zener Diodes Replacement Considerations

Equivalent parts include the JAN, JANTX, and JANTXV prefixed versions of the 1N4565 series. Surface mount equivalents are available in the DO-213AA package using the UR-1 suffix.
