1N4575A

Single Zener Diodes Overview

The Microchip Technology 1N4575A is a 6.4 V temperature compensated Zener reference diode housed in a DO-7 (DO-204AA) glass axial-leaded package. It operates with a test current of 2.0 mA and exhibits a maximum temperature coefficient of 0.01%/°C (0.64 mV/°C). The device maintains a maximum reverse current of 2 µA at 3 V and features a dynamic impedance of 50 Ohms at the specified test current. It supports an operating temperature range from -55°C to +100°C, with a DC power dissipation rating of 500 mW.

Single Zener Diodes Feature Summary

• Provides minimal voltage change over a broad operating temperature range for instrumentation and other circuit designs requiring a voltage reference
• Internal metallurgical bonded construction for enhanced reliability
• Flexible axial-leaded mounting terminals suitable for through-hole applications

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Temperature-compensated reference designs
• Precision analog signal conditioning

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 aligns with the target PCB layout constraints. Ensure the operating current remains within the specified 2.0 mA to maintain optimal voltage-temperature stability and prevent exceeding the recommended power dissipation limits during operation.

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 appropriate for designs needing a 2.0 mA test current and 50 Ohm dynamic impedance. Consider alternative series members if different temperature coefficients or test currents are necessary for the specific application requirements.

Single Zener Diodes FAQ

What is the maximum temperature coefficient for the 1N4575A?

The maximum temperature coefficient is 0.01%/°C, which corresponds to 0.64 mV/°C.

Is the 1N4575A radiation hardened?

Standard 1N4575A parts are not radiation hardened. Radiation hardened versions are designated with the 'RH' prefix instead of '1N', such as RH4575A.
