JAN1N4484CUS

Single Zener Diodes Overview

The JAN1N4484CUS is a surface mount Zener voltage regulator with a nominal breakdown voltage of 62V and a power dissipation rating of 1.5W at 25°C ambient temperature. It features a 2% tolerance on the Zener voltage, a maximum dynamic impedance of 80 Ohms at the test current of 4.0 mA, and a maximum reverse leakage current of 0.25 µA at 49.6V. The device operates within a junction and storage temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Void-less hermetically sealed glass package with internal metallurgical bonds for high reliability.
• Military qualification per MIL-PRF-19500/406 for applications where failure cannot be tolerated.
• Triple-layer passivation and robust construction resistant to ESD.

Single Zener Diodes Applications

• High-reliability voltage regulation in aerospace and defense systems.
• Circuit protection requiring radiation hardness and broad operating temperature stability.
• Precision reference voltage generation in military-grade electronic assemblies.

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level and RoHS compliance status. Confirm the package type corresponds to the D-5A MELF form factor. Ensure procurement channels provide documentation verifying the MIL-PRF-19500/406 qualification level appropriate for the intended mission profile.

Single Zener Diodes Selection Notes

Select this component when a 62V Zener voltage with tight 2% tolerance is required in a surface mount configuration. Consider the 1.5W steady-state power dissipation limit and the thermal resistance characteristics for heat management. Verify compatibility with the available military qualification levels against system reliability requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of void-less hermetically sealed surface mount Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with standard 5%, 2%, and 1% tolerances. These devices are designed as surface mount equivalents to popular JEDEC registered axial lead series.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4484DUS (1% tolerance) and JAN1N4484CUS (2% tolerance). Verify that any substitute maintains the same MIL-PRF-19500/406 qualification level and D-5A MELF package dimensions.
