1N4565AE3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4565AE3/TR is a 6.4 V temperature compensated Zener reference diode housed in a DO-7 (DO-204AA) glass axial-leaded package. It operates at a test current of 0.5 mA with a maximum voltage temperature coefficient of 0.01%/°C and a dynamic impedance of 200 Ohms. The device features a reverse current of 2 µA at 3 V and supports an operating temperature range from -65°C to +175°C. The 'TR' suffix indicates tape and reel packaging compliant with EIA-296 standards.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation and circuit designs requiring a stable voltage reference.
• Features internal metallurgical bonding within a hermetically sealed glass case, ensuring robustness against environmental factors.
• Offers flexible axial-leaded mounting terminals suitable for through-hole applications.

Single Zener Diodes Applications

• Instrumentation circuits requiring precise voltage references
• Electronic designs demanding low voltage drift across wide temperature ranges
• Military and aerospace systems utilizing qualified reference components

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes required for your application, as the datasheet indicates that military qualifications require JAN, JANTX, or JANTXV prefixes alongside the '-1' suffix. Confirm that the 'TR' suffix aligns with your automated assembly equipment requirements. Ensure the component meets the necessary JEDEC registration standards for your project specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with a 0.01%/°C temperature coefficient is required. The 0.5 mA test current makes it suitable for low-power applications compared to higher current variants in the series. Consider the DO-7 package dimensions and axial lead configuration for PCB layout compatibility. Verify if tighter voltage tolerances are needed, which may require additional suffix designations beyond the standard part number.

Single Zener Diodes Part Context

This device belongs to the 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes originally developed by Microsemi's Scottsdale Division. The series provides various temperature coefficients ranging from 0.01%/°C down to 0.0005%/°C at different operating currents. These diodes are JEDEC registered and offer options for military qualifications, serving as stable voltage references in precision analog circuits.

Single Zener Diodes Replacement Considerations

Direct replacements within the same series include other 1N456x devices with matching 0.5 mA test currents, such as the 1N4566A or 1N4567A, though their temperature coefficients differ. For identical electrical performance, verify the exact temperature coefficient and impedance requirements against the datasheet table. Military equivalents require specific JAN/JANTX prefixes and the '-1' suffix for metallurgical bonding.
