1N4571E3/TR

Single Zener Diodes Overview

The Microchip Technology 1N4571E3/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum temperature coefficient of 0.005 %/°C (0.32 mV/°C). It operates at a test current of 1.0 mA, features a maximum reverse current of 2 µA at 3 V, and has a dynamic impedance of 100 Ω. The device dissipates 500 mW in a hermetically sealed DO-7 glass axial-leaded package.

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

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape-and-reel packaging and lead-free compliance. Ensure the selected part number matches the required military or commercial qualification level, as prefixes such as JAN or JANTX denote distinct reliability standards not inherent to the base model designation.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.005 %/°C temperature coefficient is required. Confirm that the 1.0 mA test current aligns with the target circuit's power dissipation limits. Verify package compatibility with the DO-7 footprint and ensure the 500 mW power rating suits the thermal environment.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A series of zero-TC reference diodes. These components are designed to provide stable reference voltages with tight tolerance options. The series includes variants with different test currents ranging from 0.5 mA to 4.0 mA to accommodate various stability and power requirements.

Single Zener Diodes Replacement Considerations
