Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The "-TP" designation indicates RoHS compliance and lead-free finish. Confirm packaging quantities, as Tape & Reel options vary between 3Kpcs and 10Kpcs per reel depending on the full part number variant. Ensure sourcing from authorized distributors to guarantee genuine parts and traceability.

Single Diodes Selection Notes

Select this component for designs requiring a compact SOD-123 footprint with fast switching capabilities. It serves as a surface-mount alternative to through-hole equivalents like the 1N4148. Consider the 100V reverse voltage rating and 250mA continuous current limit when sizing for load requirements. Verify thermal management needs based on the 250°C/W junction-to-ambient thermal resistance.

Single Diodes Part Context

This device belongs to the standard small-signal switching diode family, functionally equivalent to the industry-standard 1N4148 but packaged for surface mount technology. The SOD-123 form factor allows for higher density PCB layouts compared to axial leads. MCC produces this series to meet modern manufacturing requirements for automated assembly lines while maintaining high-speed performance metrics.

Single Diodes Replacement Considerations

Direct functional substitutes include other SOD-123 packaged switching diodes with matching 100V and 250mA ratings, such as the 1N4148WS or BAS16 variants, provided pinout compatibility is verified.
