1N4574

Single Zener Diodes Overview

The Microchip Technology 1N4574 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 1.0 mA with a maximum temperature coefficient of 0.0005%/°C. The device provides minimal voltage change over a broad operating temperature range, featuring internal metallurgical bonding and hermetically sealed construction.

Single Zener Diodes Feature Summary

• Provides nominal 6.4 V reference voltage with tight tolerance options
• Features extremely low temperature coefficient for stable performance
• Constructed with internal metallurgical bonding in a hermetically sealed glass case

Single Zener Diodes Applications

• Instrumentation requiring precise voltage references
• Circuit designs demanding minimal voltage change across temperature ranges
• Military and aerospace applications qualifying to MIL-PRF-19500/452 standards

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for military qualifications or tighter voltage tolerances when ordering. Confirm that the selected part number aligns with the required JEDEC registration and package style. Ensure the operating test current matches the datasheet specifications for optimal voltage-temperature stability during integration.

Single Zener Diodes Selection Notes

Select this component for applications requiring high thermal stability near the 6.4 V nominal point. Consider the available test currents ranging from 0.5 mA to 4.0 mA if different power dissipation profiles are needed. Evaluate the need for military prefixes or radiation-hardened variants based on the operational environment constraints.

Single Zener Diodes Part Context

This device belongs to the popular 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. The series offers a selection of both 6.4 V nominal voltages and varying temperature coefficients down to 0.0005%/°C. These components are designed for applications where minimal voltage drift with temperature is critical.

Single Zener Diodes Replacement Considerations

Equivalent parts within the 1N4565 through 1N4584A-1 series may be considered if they match the required temperature coefficient and test current specifications. Military equivalents can be identified by adding JAN, JANTX, or JANTXV prefixes to the base part number.
