1N4574A/TR

Single Zener Diodes Overview

The Microchip Technology 1N4574A/TR is a 6.4 Volt Temperature Compensated Zener Reference Diode housed in a DO-7 (DO-204AA) glass axial-leaded package. It features an internal metallurgical bond and operates at a test current of 1.0 mA with a maximum temperature coefficient of 0.0005%/°C. The device provides minimal voltage change over a broad operating temperature range, ensuring high stability for precision applications.

Single Zener Diodes Feature Summary

• Nominal 6.4 V reference voltage with tight tolerance options
• Internal metallurgical bonded construction for reliability
• Low temperature coefficient for stable performance across temperatures
• Flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation requiring precise voltage references
• Circuit designs demanding minimal voltage drift
• Temperature-compensated reference circuits

Single Zener Diodes Procurement Notes

Verify the TR suffix indicates tape and reel packaging per EIA-296 standards. Confirm the part number matches the specific JEDEC registration and temperature coefficient requirements. Ensure compatibility with MIL-PRF-19500/452 if military qualification is needed by checking for appropriate prefixes or suffixes.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference with low temperature drift is required. Consider the 1.0 mA operating current and DO-7 package constraints. Evaluate tighter tolerance needs using hyphenated suffixes. Verify radiation hardened alternatives if applicable.

Single Zener Diodes Part Context

Part of the 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes. Offers various operating currents and temperature coefficients. Available in military qualifications with specific prefixes. Microsemi provides other Zener products up to 200 V.

Single Zener Diodes Replacement Considerations

Check for JAN, JANTX, or JANTXV prefixed equivalents for military specs. Surface mount DO-213AA versions exist with UR-1 suffix. Consult separate datasheets for DO-35 or JANS variants.
