1N4567

Single Zener Diodes Overview

The Microchip Technology 1N4567 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 current of 2 µA at 3 V, and has a dynamic impedance of 200 Ohms. The device is housed in a hermetically sealed DO-7 (DO-204AA) glass package.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the component was originally produced by Microsemi and is now part of Microchip Technology. Confirm that the DO-7 package matches your board layout requirements. Ensure the ordering suffix aligns with any required military qualifications or tolerance specifications.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.002 %/°C temperature coefficient is required. Verify that the 0.5 mA test current suits your biasing network. Consider tighter tolerance suffixes if standard 5% voltage accuracy is insufficient for your application.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These components provide various temperature coefficients and operating currents while maintaining a consistent 6.4 V nominal voltage across the family.

Single Zener Diodes FAQ

What is the maximum operating temperature range?

The device supports an operating temperature range from -65°C to +175°C.

How is polarity identified on the component?

The cathode is marked with a band; the reference diode must be operated with the banded end positive with respect to the opposite end.
