• High-speed switching applications

Single Diodes Procurement Notes

Verify the specific JAN or commercial grade suffix when ordering, as the base part number may refer to multiple reliability levels. Confirm the 3-pin ceramic package style matches the design constraints. Check for recent Product Change Notifications regarding manufacturing updates. Ensure the procurement channel provides traceability documentation required for aerospace or military specifications associated with this component family.

Single Diodes Selection Notes

Select this component when a high-reliability ceramic package is mandatory for signal switching tasks. The 75V rating suits low-voltage digital logic interfaces. Compare against standard DO-35 glass packages if weight or volume is not a primary constraint. Verify that the 200mA continuous current meets the load requirements without excessive thermal buildup in the enclosed ceramic housing.

Single Diodes Part Context

This component belongs to the broader 1N4148 series of fast switching diodes manufactured by Microchip Technology. While the standard 1N4148 typically uses a glass DO-35 package, the UB2 designation indicates a distinct 3-pin ceramic construction. This variant targets environments requiring higher mechanical stability than standard axial leads provide.
