1N4572-1

Single Zener Diodes Overview

The Microchip Technology 1N4572-1 is a temperature-compensated Zener reference diode featuring a nominal voltage of 6.4 V and a package style of DO-35 (DO-204AH). It operates with a test current of 1 mA and has a maximum power dissipation of 500 mW. The device offers a standard voltage tolerance of ±5%, with tighter tolerances available at lower voltages within the series. It supports an internal metallurgical bond construction, indicated by the '-1' suffix, which enhances mechanical stability for demanding environments.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change across operating temperatures
• Internal metallurgical bond construction for enhanced mechanical reliability
• Zero-TC reference characteristics providing stable voltage output

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature compensation networks
• Military and aerospace electronic systems

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N4565 through 1N4584A-1 series was historically associated with Microsemi, now part of Microchip Technology. Confirm that the '-1' suffix correctly denotes the internal metallurgical bond option required for your application's mechanical stress requirements. Ensure compatibility with MIL-PRF-19500/452 qualifications if military-grade performance is specified in the design documentation.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference with low temperature coefficient is required in a glass axial-leaded package. The internal metallurgical bond makes it suitable for applications subject to vibration or shock. Consider the 1 mA test current requirement for biasing circuitry. Evaluate the DO-35 package constraints against board space limitations and thermal management needs compared to surface mount alternatives.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. These devices provide a selection of nominal voltages and temperature coefficients as low as 0.0005%/°C. The series is designed for applications requiring minimal voltage change with temperature variations, offering both standard and tighter tolerance options.
