1N4583A-1

Single Zener Diodes Overview

The Microchip Technology 1N4583A-1 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 temperature coefficient of 0.001%/°C (0.06 mV/°C). The device features a maximum reverse leakage current of 2 µA at 3 V and a dynamic impedance of 25 Ω at the test current. It supports an operating temperature range from -55°C to +100°C and handles up to 500 mW DC power dissipation.

Single Zener Diodes Feature Summary

• Provides stable voltage reference with minimal change over broad temperature ranges
• Features internal metallurgical bonding for structural integrity
• Offers flexible axial-leaded mounting terminals for through-hole integration

Single Zener Diodes Applications

• Instrumentation circuits requiring precise voltage references
• Temperature compensated power supply designs
• Precision measurement equipment calibration

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 matches your board layout constraints. Ensure the operating current aligns with the specified 4.0 mA test condition 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 nominal 6.4 V reference with low temperature drift is required. Compare the 0.001%/°C coefficient against other series members like 1N4582A or 1N4584A based on drift sensitivity needs. Consider the 4.0 mA test current requirement for biasing circuit design. Evaluate the DO-7 package size against available PCB space.

Single Zener Diodes Part Context

This part belongs to the 1N4565 thru 1N4584A-1 series of Zero-TC Reference Diodes manufactured by Microsemi (now Microchip Technology). The series provides various temperature coefficients and test currents while maintaining a consistent 6.4 V nominal voltage. These devices are designed for high-stability applications where voltage drift due to temperature changes must be minimized.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include 1N4582A (0.002%/°C) or 1N4584A (0.0005%/°C) if different drift characteristics are acceptable. Military qualified equivalents use JAN, JANTX, or JANTXV prefixes. Surface mount alternatives exist in the DO-213AA package with the UR-1 suffix.
