1N4584A

Single Zener Diodes Overview

The Microchip Technology 1N4584A 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 0.0005%/°C. The device features a nominal voltage tolerance of ±5%, a maximum reverse current of 2 µA at 3 V, and a dynamic impedance of 25 Ω. It supports an operating temperature range from -55°C to +100°C and offers optional military qualifications via JAN, JANTX, or JANTXV prefixes.

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 suitable for through-hole integration

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift
• Precision measurement systems

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for military qualification (JAN, JANTX, JANTXV) if applicable, as standard JEDEC registration does not include these prefixes. Confirm the desired voltage tolerance percentage if tighter than the standard ±5% specification. Ensure the ordering suffix matches the required package style and testing conditions specified in the manufacturer's documentation.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with ultra-low temperature drift is required. The 4.0 mA test current setting distinguishes it from lower-current variants in the series. Consider the DO-7 package dimensions for board layout constraints. Verify that the operating environment stays within the specified temperature range for optimal stability performance.

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 ranging from 0.01%/°C to 0.0005%/°C while maintaining a consistent 6.4 V nominal voltage. These devices are designed for high-stability applications where voltage consistency across temperature variations is critical.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 6.4 V Zener reference diodes with similar temperature coefficients and power ratings. Check for compatible packages such as DO-35 or surface mount equivalents like DO-213AA if space constraints differ. Military versions may require specific prefixes like JANTX1N4584A.
