1N4568A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4568A/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 tight voltage tolerance of ±1% and an extremely low voltage temperature coefficient of 0.001%/°C, ensuring minimal voltage drift across operating conditions. The device operates within a junction temperature range of -55°C to +100°C and dissipates up to 500 mW. Packaged in the DO-35-2 axial leaded format for through-hole mounting, it exhibits a maximum reverse leakage current of 2 µA and a Zener impedance of 200 Ohms at the specified test current.

Single Zener Diodes Feature Summary

• Temperature compensated design providing stable reference voltage with minimal drift over temperature variations
• High precision voltage tolerance of ±1% for accurate regulation applications
• Internal metallurgical bond construction available via suffix options for enhanced mechanical reliability

Single Zener Diodes Applications

• Precision voltage reference circuits requiring high stability
• Temperature compensated regulator designs
• General purpose regulation in sensitive analog systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the required military or commercial qualification levels, as prefixes such as JAN or JANTX denote distinct reliability standards. Confirm that the reel packaging matches the automated assembly requirements. Ensure the selected variant meets the necessary environmental testing criteria for the intended operational temperature range and mechanical stress conditions.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is needed with superior thermal performance compared to standard Zener diodes. The 0.5 mA test current allows for lower power consumption in battery-operated or low-power designs. Consider the DO-35 package constraints for board space and verify that the 200 Ohm impedance is acceptable for the dynamic load requirements of the target circuit.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A series of Zero-Temperature Coefficient (Zero-TC) Reference Diodes manufactured by Microchip Technology. These devices are engineered to provide a nominal 6.4 V output with exceptionally low temperature coefficients, making them suitable for high-precision applications where voltage stability is critical despite ambient temperature fluctuations.

Single Zener Diodes Replacement Considerations

Direct substitutes include other parts from the 1N4565–1N4584A series with matching voltage and tolerance specifications. Military-grade equivalents may require JAN, JANTX, or JANTXV prefixes. Surface mount alternatives exist in the DO-213AA package with appropriate UR-1 suffixes for equivalent electrical performance.
