1N4567A

Single Zener Diodes Overview

The Microchip Technology 1N4567A is a temperature compensated Zener reference diode with a nominal voltage of 6.4 V and a tolerance of ±5%. It operates at a test current (IZT) of 0.5 mA, providing a maximum temperature coefficient of 0.002%/°C (±0.13 mV/°C). The device features a maximum reverse leakage current of 2 µA at 3 V and a dynamic impedance of 200 Ω. It is housed in a hermetically sealed glass DO-7 (DO-204AA) axial-leaded package.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges
• Internal metallurgical bonding within a hermetically sealed glass case
• ESD nonsensitive per MIL-STD-750 Method 1020

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 manufacturer lineage, as the part originates from Microsemi now under Microchip Technology. Confirm that the ordering suffix does not alter the electrical function or package type unless explicitly documented. Ensure compliance requirements match the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with tight temperature stability is required. The 0.5 mA test current suits low-power applications. Verify if military qualifications are necessary, which require adding JAN or JANTX prefixes to the base part number.

Single Zener Diodes Part Context

This device belongs to the 1N4565 through 1N4584A-1 series of zero-TC reference diodes. The series offers various temperature coefficients and test currents ranging from 0.5 mA to 4.0 mA. All devices share the same nominal 6.4 V output and DO-7 package form factor.
