1N4572

Single Zener Diodes Overview

The Microchip Technology 1N4572 is a 6.4 V temperature compensated Zener reference diode housed in a DO-7 (DO-204AA) glass axial-leaded package. It operates at a test current of 1.0 mA with a maximum voltage temperature coefficient of 0.002%/°C (0.13 mV/°C). The device features a nominal voltage tolerance of ±5%, a maximum reverse current of 2 µA at 3 V, and a dynamic impedance of 100 Ω. It supports an operating temperature range from -55°C to +100°C and dissipates up to 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 circuits requiring stable voltage references
• Precision measurement equipment
• Temperature-compensated power supply designs

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the 1N4572 designation originates from Microsemi specifications but may be produced by other entities under license. Confirm that the component matches the JEDEC registered 1N4565 thru 1N4584 series characteristics. Ensure the package corresponds to the DO-7 form factor and check for any suffixes indicating military qualifications or tape-and-reel packaging options.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.002%/°C temperature coefficient is required. It is appropriate for designs needing a 1.0 mA test current operation point. Consider tighter tolerance variants if standard ±5% voltage accuracy is insufficient for the application requirements.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes. The series provides a selection of 6.4 V nominal voltages with various temperature coefficients ranging from 0.01%/°C down to 0.0005%/°C. These glass axial-leaded diodes are designed for applications demanding high stability and low voltage drift across temperature variations.
