1N4566AE3

Single Zener Diodes Overview

The Microchip Technology 1N4566AE3/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a test current of 0.5 mA. It features a maximum temperature coefficient of 0.005%/°C (0.32 mV/°C) and a dynamic impedance of 200 Ohms at the test current. The device operates within a temperature range of -55°C to +100°C, has a maximum reverse current of 2 µA at 3 V, and is housed in a DO-7 (DO-204AA) glass axial-leaded package.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over operating ranges
• Internal metallurgical bonding for structural integrity
• Hermetically sealed glass case construction

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 suffix configuration against official datasheets to confirm tolerance levels and military qualification status. Ensure the ordering code matches the required temperature coefficient and package type. Confirm availability through authorized distributors as supply may be restricted.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.005%/°C temperature coefficient is required. Verify that the 0.5 mA test current aligns with circuit power constraints. Consider tighter tolerance suffixes if standard specifications are insufficient for precision requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4565 thru 1N4584A series of zero-TC reference diodes. These devices provide nominal 6.4 V outputs with various temperature coefficients ranging from 0.01%/°C to 0.0005%/°C. The series supports multiple operating currents and offers military qualifications under MIL-PRF-19500/452 standards.
