Single Diodes Procurement Notes

Verify the specific ordering suffix against official Panjit documentation to ensure correct packaging configuration. Confirm RoHS2.0 and halogen-free status requirements match project specifications. Validate that the SOD-123 footprint aligns with the target PCB layout before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a fast-switching diode with low junction capacitance is required in a compact surface mount form factor. The AEC-Q101 qualification makes it appropriate for automotive environments. Ensure thermal management accounts for the 410 mW dissipation limit and derating curves above 25°C ambient temperature.

Single Diodes Part Context

This part belongs to the 1N4148 family of silicon epitaxial planar switching diodes. It serves as a surface-mount alternative to through-hole variants like the DO-35 packaged 1N4148. The SOD-123 package provides electrical equivalence to standard JEDEC specifications while offering improved suitability for automated assembly processes.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4148W or 1N4148WS series devices in the SOD-123 package. Verify pinout compatibility and ensure replacement parts meet the same 100 V reverse voltage and 4 ns recovery time specifications.
