1N4568A

Single Zener Diodes Overview

The Microchip Technology 1N4568A is a 6.4 V temperature compensated Zener reference diode in a DO-7 (DO-204AA) glass axial-leaded package. It operates at a test current of 0.5 mA with a maximum reverse current of 2 µA at 3 V and dynamic impedance of 200 Ohms. The device features a temperature coefficient of 0.001 %/°C, operating within a range of -55°C to +100°C. DC power dissipation is rated at 500 mW.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation applications
• Features internal metallurgical bonding for enhanced reliability
• Offers flexible axial-leaded mounting terminals suitable for through-hole integration

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low voltage drift with temperature
• Precision analog signal processing systems

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the datasheet, as military qualifications require JAN, JANTX, or JANTXV prefixes combined with the -1 suffix. Confirm RoHS compliance status, as standard versions may not meet current environmental directives. Ensure ordering specifications match the required temperature coefficient and tolerance levels defined in the electrical characteristics table.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with tight temperature stability is required. The 0.5 mA test current option suits low-power applications. Consider tighter tolerance suffixes if standard manufacturing variations exceed design limits. Verify that the DO-7 package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

Part of the 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes. This family provides various temperature coefficients ranging from 0.01%/°C to 0.0005%/°C across different operating currents. The series is JEDEC registered and available in multiple packages including DO-35 and surface mount DO-213AA variants.

Single Zener Diodes Replacement Considerations

Direct substitutes include other members of the 1N4565-1N4584A series with matching 6.4 V nominal voltage. Equivalent parts must be verified for identical temperature coefficients and test currents. Military qualified equivalents are available with appropriate JAN/JANTX prefixes.
