1N4583

Single Zener Diodes Overview

The Microchip Technology 1N4583 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 4.0 mA with a maximum voltage temperature coefficient of 0.001%/°C. The device features a nominal reverse current of 2.0 µA at 3 V and a maximum dynamic impedance of 25 Ohms at the test current. It supports an operating temperature range from -55°C to +100°C.

Single Zener Diodes Feature Summary

• Provides stable voltage reference with minimal change over broad operating temperature ranges
• Features internal metallurgical bonding for enhanced reliability
• Offers flexible axial-leaded mounting terminals for circuit integration

Single Zener Diodes Applications

• Instrumentation requiring precise voltage references
• Circuit designs demanding low temperature drift
• Temperature compensated reference applications

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 matches the specified 4.0 mA for optimal stability. Check for RoHS compliance status as standard versions may not meet all environmental directives.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.001%/°C temperature coefficient is required. Compare against other series members like 1N4582 or 1N4584 if different temperature coefficients or test currents better suit the design. Consider the DO-7 package size relative to available board space. Verify that the 25 Ohm dynamic impedance meets the noise and regulation requirements of the application.

Single Zener Diodes Part Context

This part belongs to the 1N4565 through 1N4584A-1 series of Zero-TC Reference Diodes. The series provides various combinations of 6.4 V nominal voltages and temperature coefficients ranging from 0.01%/°C to 0.0005%/°C. These diodes are designed for high-stability applications where voltage drift due to temperature changes must be minimized.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N4582 and 1N4584, which share the 4.0 mA test current but offer different temperature coefficients. Military qualified versions such as JANTX1N4583A-1 provide the same electrical characteristics with enhanced reliability standards.
