1N4569A-1

Single Zener Diodes Overview

The Microchip Technology 1N4569A-1 is a temperature-compensated Zener reference diode featuring a nominal voltage of 6.4 V and a tight tolerance of 0.1%. Housed in a DO-35 glass axial package with an internal metallurgical bond, it operates at a test current of 0.5 mA. The device dissipates up to 500 mW and maintains a low voltage temperature coefficient of 0.001%/°C. It supports a wide operating temperature range from -55°C to +100°C.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage drift across varying thermal conditions
• Internal metallurgical bond construction for enhanced mechanical stability
• High precision voltage regulation with tight initial tolerance specifications

Single Zener Diodes Applications

• Precision voltage reference circuits requiring stable DC levels
• Temperature compensation networks in analog signal conditioning
• Reference sources for high-resolution data conversion systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required military or commercial qualification standards. Confirm that the DO-35 through-hole package aligns with the target PCB layout constraints. Check for RoHS compliance status as indicated in official documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 6.4 V reference is needed with superior thermal stability compared to standard Zener diodes. The 0.5 mA test current offers a balance between power consumption and regulation accuracy. Ensure the application environment stays within the specified -55°C to +100°C operational limits for guaranteed performance.

Single Zener Diodes Part Context

This part belongs to the 1N4565A-1 through 1N4584A-1 series of Zero-TC Reference Diodes produced by Microchip Technology. These devices are designed to provide highly stable voltage references with near-zero temperature coefficients. The series utilizes glass axial-leaded packages suitable for robust electronic assembly in demanding environments.

Single Zener Diodes Replacement Considerations

Direct substitutes include other temperature-compensated Zener diodes with identical 6.4 V nominal voltage and similar DO-35 packaging. Verify that alternative components match the 0.1% tolerance and 0.001%/°C temperature coefficient requirements to maintain circuit accuracy.
