1N4573A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4573A-1/TR is a temperature-compensated Zener diode designed for precision voltage reference applications. It features a nominal Zener voltage of 6.4V with a tight tolerance of +/-0.1% at a test current of 1mA. The device utilizes a round-end construction to minimize mechanical stress effects on electrical characteristics. It is housed in the DO-213AA-2 (SOD-80) surface-mount package and operates within an extended temperature range from -65°C to +175°C, ensuring stability in demanding environments.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage reference performance across wide thermal ranges
• High precision voltage tolerance of +/-0.1% at specified test current
• Round-end construction reduces sensitivity to mechanical stress variations

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm package type and tolerance grade. Ensure compatibility with surface-mount assembly processes given the DO-213AA-2 footprint. Confirm environmental compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering.

Single Zener Diodes Selection Notes

Select this component when high accuracy and low temperature drift are critical requirements. The +/-0.1% tolerance distinguishes it from standard Zener diodes. Consider the SMD package format for automated assembly needs. Evaluate thermal management requirements as the device operates up to +175°C.
