1N4980US

Single Zener Diodes Overview

The Microchip Technology 1N4980US is a surface mount Zener voltage regulator with an 82 V nominal breakdown voltage. It operates within a -65°C to +175°C temperature range and dissipates up to 5 Watts of power. The device features a standard 5% voltage tolerance, a test current of 15 mA, and a maximum reverse leakage current of 2 µA at the rated voltage. Its dynamic impedance is specified at 80 Ohms, and it supports a continuous current of 58 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass package for high-reliability applications
• Military qualified to MIL-PRF-19500/356 standards
• Internal metallurgical bonds ensure robust construction
• Inherently radiation hard

Single Zener Diodes Applications

• High-reliability military systems
• Spacecraft electronics
• Critical aerospace circuits

Single Zener Diodes Procurement Notes

Verify that the component matches the specific 1N4980US part number and confirms compliance with MIL-PRF-19500/356. Ensure the supplier provides documentation validating the hermetic seal and voidless-glass construction. Confirm the manufacturer origin is Microchip or authorized Microsemi production lines to guarantee authenticity and traceability.

Single Zener Diodes Selection Notes

Select this component when a surface-mount Zener diode requires military-grade reliability and radiation hardness. It is suitable for designs needing a stable 82 V reference in extreme environments. Consider the 5 W power dissipation capability and the specific E-package dimensions during PCB layout planning.

Single Zener Diodes Part Context

This device belongs to the 1N4954US through 1N4996US series of surface mount Zener regulators. These components share identical mechanical and electrical characteristics, differing only in their specific Zener voltage ratings. The series is designed to replace traditional axial-leaded parts in compact, high-density circuit boards requiring rugged performance.

Single Zener Diodes Replacement Considerations

Axial-leaded equivalents are available by removing the US suffix (e.g., 1N4980). Other voltages within the 1N4954US to 1N4996US series can be selected based on required regulation levels.
