1N4568

Single Zener Diodes Overview

The Microchip Technology 1N4568 is a 6.4 V temperature compensated Zener reference diode housed in a DO-7 (DO-204AA) glass axial-leaded package. It operates at a test current of 0.5 mA with a maximum reverse leakage current of 2 µA at 3 Vdc and a dynamic impedance of 200 Ohms. The device features a temperature coefficient of 0.001%/°C (0.06 mV/°C) and supports an operating temperature range from 0°C to +75°C. It provides minimal voltage change over the specified temperature range for precision circuit designs.

Single Zener Diodes Feature Summary

• Temperature compensated design providing minimal voltage change across the operating temperature range
• Internal metallurgical bond construction for enhanced reliability
• JEDEC registered part number within the 1N4565 through 1N4584 series

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Precision analog circuit designs
• Temperature sensitive measurement systems

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for military qualifications or tighter voltage tolerances when ordering, as standard JEDEC registration applies to the base model. Confirm package type availability if surface mount equivalents are required instead of the standard axial leaded configuration.

Single Zener Diodes Selection Notes

Select this component for applications demanding low temperature drift at a nominal 6.4 V output. Ensure the operating current aligns with the specified 0.5 mA test condition to maintain optimal voltage-temperature stability and prevent excessive power dissipation.

Single Zener Diodes Part Context

This device belongs to the popular 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microsemi. The series offers various temperature coefficients and operating currents to suit different precision reference needs while maintaining a consistent 6.4 V nominal voltage.

Single Zener Diodes Replacement Considerations

Military qualified equivalents are available by adding JAN, JANTX, JANTXV, or JANS prefixes along with the “-1” suffix, such as JANTX1N4568A-1.
