JANTX1N4956CUS

Single Zener Diodes Overview

The JANTX1N4956CUS is a high-reliability Zener diode manufactured by Microchip Technology (formerly Microsemi). It features an 8.2V nominal Zener voltage with a 5% tolerance and operates at a test current of 175mA. The device provides a maximum dynamic impedance of 32 Ohms and handles a power dissipation of 0.5W. Designed for robust performance, it supports a wide operating temperature range from -65°C to +200°C. The component utilizes a hermetically sealed plastic E package (DO-35) with axial leads, ensuring isolation and durability in demanding environments.

Single Zener Diodes Feature Summary

• Hermetically sealed construction for environmental protection
• High thermal stability supporting extended temperature ranges
• Axial leaded configuration for through-hole mounting

Single Zener Diodes Applications

• Military aerospace electronic systems
• Spacecraft power regulation circuits
• High-reliability industrial control equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix 'CUS' against official Microchip documentation to confirm exact manufacturing lot specifications and compliance status. Ensure procurement channels are authorized to guarantee authenticity for this high-reliability grade. Confirm that the axial lead form factor matches the target PCB layout requirements before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, axial-lead Zener diode is required for extreme temperature environments up to 200°C. The 8.2V rating and 0.5W power dissipation define its operational limits. Verify that the 32 Ohm dynamic impedance meets the circuit's noise and regulation sensitivity requirements compared to lower-impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N4956 series of high-reliability Zener diodes produced by Microchip. The 'JANTX' prefix indicates a specific military-grade screening level within the broader product family. These components are engineered for applications where standard commercial parts would fail due to harsh environmental conditions or strict reliability mandates.

Single Zener Diodes Replacement Considerations

Direct substitutes include the JANTX1N4956 without the 'CUS' suffix if packaging variations are acceptable. Cross-reference with other manufacturers' DO-35 hermetic packages only if electrical parameters such as voltage tolerance and power dissipation are strictly matched.
