1N4575

Single Zener Diodes Overview

The Microchip Technology 1N4575 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 2.0 mA with a maximum voltage temperature coefficient of 0.01%/°C and a dynamic impedance of 50 Ohms. The device supports an operating temperature range from -65°C to +175°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

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 suffix requirements for military qualifications or tighter voltage tolerances when ordering. Confirm that the DO-7 package dimensions align with your PCB layout constraints. Ensure the operating current remains within specified limits to maintain optimal voltage-temperature stability during implementation.

Single Zener Diodes Selection Notes

Select this component when a nominal 6.4 V reference with a 0.01%/°C temperature coefficient is required. It is suitable for designs needing a 2.0 mA test current and hermetically sealed glass packaging. Consider alternative series members if different temperature coefficients or test currents are necessary for the application.

Single Zener Diodes Part Context

This part belongs to the popular 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. The series provides various selections of 6.4 V nominal voltages and temperature coefficients ranging from 0.01%/°C down to 0.0005%/°C. These diodes are designed for high-reliability applications requiring precise voltage regulation.

Single Zener Diodes Replacement Considerations

JAN, JANTX, and JANTXV prefixed versions are available for military qualification. Tighter voltage tolerance options can be obtained by adding hyphenated percentage suffixes to the part number.
