1N4565

Single Zener Diodes Overview

The Microchip Technology 1N4565 is a temperature compensated Zener reference diode with a nominal voltage of 6.4 V and a tolerance of +/- 5%. It operates at a test current (IZT) of 0.5 mA, featuring a maximum temperature coefficient of +/- 0.01%/°C and a dynamic impedance (ZZT) of 200 Ohms. The device has a maximum reverse leakage current of 2 µA at 3 Vdc. It is housed in a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package, supporting an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation applications
• Features internal metallurgical bonding for enhanced stability
• Offers flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Circuit designs demanding low voltage drift across temperature variations
• Military qualification applications via JAN/JANTX prefixes

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as historical documentation lists Microsemi while current listings may indicate Microchip Technology. Confirm the package type matches the required DO-7 or DO-35 form factor. Ensure the ordering suffix aligns with desired military qualifications if applicable. Check for RoHS compliance status as older datasheets may not reflect current environmental regulations.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with a 0.5 mA test current is required. It is suitable for designs needing a temperature coefficient up to 0.01%/°C. Consider tighter tolerance suffixes if standard 5% variation is insufficient. Verify that the axial leaded package fits the PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes. The series provides various temperature coefficients and operating currents ranging from 0.5 mA to 4.00 mA. All parts share a nominal 6.4 V output but differ in stability and impedance characteristics based on the specific JEDEC number assigned.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N4566 through 1N4584 variants, which offer different temperature coefficients and test currents. Military qualified versions are available with JAN, JANTX, or JANTXV prefixes.
