Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required radiation hardness or quality levels. Confirm that the DO-41 package dimensions match your PCB layout constraints. Ensure procurement channels provide valid traceability records for this component type.

Single Zener Diodes Selection Notes

Select this component when a stable 68V reference is required with high power handling capabilities. The 2% tolerance makes it suitable for applications needing tighter regulation than standard Zener diodes. Consider the isolated case feature if electrical isolation from the heatsink or chassis is necessary for safety or noise reduction.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes, designed for high-reliability applications. The TX suffix typically indicates enhanced screening or quality levels compared to standard commercial variants. It is part of Microchip's broader portfolio of discrete semiconductor devices used in critical infrastructure and defense electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N3040C-1/TR for standard grade and JANTXV1N3040C-1/TR for higher screening levels. Verify that any replacement maintains the 68V Zener voltage, 1W power rating, and DO-41 package form factor to ensure mechanical and electrical compatibility.
