Single Zener Diodes Procurement Notes

Verify the specific suffix designation (e.g., DUS, US) against the official datasheet to confirm package type and testing standards. Ensure procurement channels are authorized to guarantee component authenticity and traceability required for critical applications. Confirm compliance with relevant military specifications before integration into final assemblies.

Single Zener Diodes Selection Notes

Select this component when a stable 220 V reference is required in high-temperature or radiation-exposed environments. Evaluate the 5 W power dissipation capability against circuit load requirements. Consider the axial leaded package dimensions for PCB layout constraints and verify that the 550 Ohm impedance meets signal integrity needs.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes, which are characterized by enhanced reliability and strict quality control measures suitable for defense and space applications. The JANTXV designation indicates a specific level of screening and testing beyond standard commercial grades, ensuring consistent performance in mission-critical hardware.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 220 V Zener voltage, 5% tolerance, and 5 W power rating. Verify equivalent thermal ratings and package compatibility. Cross-reference with other JAN-series parts from Microchip or qualified second-source manufacturers offering identical electrical profiles and environmental certifications.
