JANS1N4484DUS

Single Zener Diodes Overview

The JANS1N4484DUS is a silicon Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 62V with a tolerance of 1%. The device is rated for a power dissipation of 1.5W and utilizes a voidless hermetically sealed glass package in the D-5A (SQ SMT) form factor. Designed for high-reliability applications, it operates within an extended temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Voidless hermetically sealed glass construction
• Triple-layer passivation for robustness
• Internal metallurgical bonds

Single Zener Diodes Applications

• Military aerospace systems
• Space-grade electronics
• High-reliability voltage regulation

Single Zener Diodes Procurement Notes

Verify authenticity through authorized channels due to military qualification requirements. Confirm specific suffix designations match project specifications. Ensure handling procedures align with hermetic seal integrity standards. Validate compliance with relevant defense procurement regulations before integration into critical systems.

Single Zener Diodes Selection Notes

Select this component for designs requiring extreme environmental resilience and long-term stability. The hermetic glass package ensures protection against moisture and contaminants. Consider the 1.5W power rating and 62V breakdown voltage when designing biasing circuits. Verify thermal management capabilities for operation at maximum junction temperatures.

Single Zener Diodes Part Context

This part belongs to the JANS series of radiation-hardened and high-reliability discrete semiconductors. It is based on the standard 1N4484 electrical characteristics but manufactured under strict quality controls for defense and space applications. The D-5A package provides a surface-mount solution compatible with automated assembly processes while maintaining hermetic sealing.

Single Zener Diodes Replacement Considerations

JANS1N4484CUS offers identical electrical performance with a 2% tolerance instead of 1%. JAN1N4484DUS/TR provides the same voltage and package but lacks the JANS military qualification level.
