1N4580

Single Zener Diodes Overview

The Microchip Technology 1N4580 is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.01 %/°C (0.64 mV/°C). It operates at a test current of 4.0 mA, features a maximum reverse current of 2 µA at 3 V, and has a dynamic impedance of 25 Ω. The device is housed in a hermetically sealed glass DO-7 (DO-204AA) package, supports an operating temperature range from -65°C to +175°C, and dissipates up to 500 mW.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bonding for structural integrity
• Hermetically sealed glass case construction
• Flexible axial-leaded mounting terminals

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for military qualifications or tape-and-reel packaging when ordering. Confirm that the selected variant matches the required temperature coefficient and tolerance specifications for your application. Ensure compatibility with the DO-7 through-hole mounting style during PCB layout.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 4.0 mA test current is required. Consider tighter tolerance options by adding percentage suffixes if standard tolerances are insufficient. Evaluate the available temperature coefficient grades across the series to match thermal stability needs.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of zero-TC reference diodes. These devices provide a selection of nominal 6.4 V voltages with varying temperature coefficients and operating currents ranging from 0.5 mA to 4.0 mA. The series includes options for military qualifications and surface mount equivalents.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4580A and variants with different tolerance suffixes such as 1N4580A-1%.
