1N4580A

Single Zener Diodes Overview

The Microchip Technology 1N4580A 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 0.01%/°C and a maximum reverse current of 2.0 µA at 3 V. The device supports an operating temperature range from -65°C to +175°C, features internal metallurgical bonding, and provides a nominal reference voltage of 6.4 V ±5%.

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
• Features flexible axial-leaded mounting terminals and nonsensitive operation to ESD per MIL-STD-750 Method 1020
• Includes internal metallurgical bond construction within a hermetically sealed glass case

Single Zener Diodes Applications

• Instrumentation circuits requiring stable voltage references
• Circuit designs demanding minimal voltage change across broad temperature ranges
• Military qualification applications via JAN, JANTX, or JANTXV prefixes

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet originates from Microsemi while the brand is listed as Microchip Technology. Confirm the package type matches the required DO-7 form factor. Ensure the operating test current aligns with the specified 4.0 mA for optimal stability. Check for military suffixes if radiation hardening or specific qualification standards are required.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with a 0.01%/°C temperature coefficient is needed. It is suitable for through-hole mounting in environments up to 175°C. Consider tighter tolerance options by adding hyphenated suffixes if standard ±5% voltage accuracy is insufficient for the application requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4565 thru 1N4584A series of Zero-TC Reference Diodes. The series offers various temperature coefficients ranging from 0.01%/°C down to 0.0005%/°C. Different operating currents are available across the series, including 0.5 mA, 1.0 mA, 2.00 mA, and 4.00 mA, allowing selection based on power dissipation and stability needs.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4580 without the 'A' suffix for standard tolerance, or variants with different temperature coefficients like the 1N4581A. Military equivalents are available with JAN, JANTX, or JANTXV prefixes.
