1N4568-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4568-1/TR is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V. It belongs to the 1N4565 through 1N4584A-1 series, designed for applications requiring minimal voltage change with temperature variations. The device features an internal metallurgical bond, indicated by the -1 suffix, and is housed in a DO-35 glass axial-leaded package. It offers a Zener reference voltage tolerance of ±5% and supports operating currents of 0.5 mA, 1.0 mA, 2.00 mA, and 4.00 mA.

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required military or commercial qualifications. Confirm that the -1 suffix denotes the internal metallurgical bond as specified in the manufacturer's documentation. Cross-reference the part number with the latest Microchip Technology product change notifications to verify current manufacturing status and any potential form-fit-function changes.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference with low temperature coefficient is required. The DO-35 package suits through-hole designs. Ensure the operating current matches one of the available options (0.5 mA, 1.0 mA, 2.00 mA, or 4.00 mA) for optimal performance. Consider the internal metallurgical bond if enhanced mechanical stability is necessary for the application environment.

Single Zener Diodes Part Context

This part is part of the popular 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These diodes are JEDEC registered and offer temperature coefficients as low as 0.0005%/°C. The series is also qualified to MIL-PRF-19500/452 with appropriate prefixes like JAN, JANTX, or JANTXV, providing options for various reliability requirements.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 6.4 V temperature-compensated Zener diodes from manufacturers such as Microsemi/Microchip. Verify package compatibility (DO-35) and electrical characteristics, specifically the temperature coefficient and test current, before substitution.
