Single Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure compatibility with UB2 package dimensions during PCB layout. Validate that the component meets required military or industrial specifications if applicable to the design constraints.

Single Diodes Selection Notes

Select this component for designs requiring fast switching speeds and low capacitance in a surface mount footprint. Consider the 75 V reverse voltage rating against circuit peak voltages. Evaluate the 200 mA forward current limit for load requirements. Compare thermal resistance values against available heat dissipation paths in the final enclosure design.

Single Diodes Part Context

This part belongs to the Microchip 1N4148 family of small signal switching diodes. It shares functional similarities with standard 1N4148 devices but is optimized for surface mount technology. The UB2 package provides a compact form factor suitable for modern high-density printed circuit board layouts.

Single Diodes Replacement Considerations

Direct substitutes include JAN1N4148UBCD/TR and JANTXV1N4148UB/TR from Microchip. Verify pinout compatibility and package dimensions before substitution. Ensure electrical parameters such as recovery time and reverse voltage meet original design specifications.
