1N4582A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4582A/TR 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 4.0 mA, featuring a maximum reverse current of 2 µA and dynamic impedance of 25 Ω. The device dissipates 500 mW and functions within a temperature range of -65°C to +175°C. Packaged in the DO-7 (DO-204AA) axial leaded format, it utilizes internal metallurgical bonding for stability.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range
• Features internal metallurgical bonding for structural integrity
• Offers flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift
• Precision analog signal conditioning

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging per EIA-296 standards. Confirm that the manufacturer designation aligns with Microsemi Scottsdale Division specifications. Ensure the component meets the required JEDEC registration for the 1N4582 series before integration into production.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.002 %/°C temperature coefficient is required. The 4.0 mA test current setting distinguishes it from lower current variants in the series. Verify that the DO-7 package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These devices are designed to provide stable reference voltages with varying temperature coefficients. The 1N4582A specifically targets applications needing tighter thermal stability than standard Zener diodes while maintaining a 6.4 V nominal output.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4582A-1 or JANTX1N4582A-1 for military qualifications. Surface mount equivalents are available by adding the UR-1 suffix, such as JANTX1N4582AUR-1.
