Single Diodes Procurement Notes

Verify the specific manufacturer part number against official Diodes Incorporated documentation to confirm availability status. Check for any Product Change Notifications or End-of-Life notices that may affect long-term supply. Ensure the ordering suffix matches the required packaging format. Confirm RoHS compliance details directly from the latest datasheet before finalizing procurement decisions.

Single Diodes Selection Notes

Select this component when a compact surface-mount switching diode with fast recovery characteristics is required. Compare the 100 V reverse voltage rating against circuit requirements to ensure adequate margin. Evaluate the 150 mA current handling capacity relative to load conditions. Consider the SOD-323 footprint compatibility during the PCB layout phase to ensure proper soldering and thermal management.

Single Diodes Part Context

This component belongs to the 1N4148 family of small signal switching diodes. It serves as a surface-mount alternative to traditional through-hole variants like the DO-35 packaged 1N4148. The device maintains similar electrical performance metrics while offering improved automation compatibility and reduced board space consumption for modern electronic assemblies.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4148WS equivalents such as those from Vishay or Taiwan Semiconductor. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same 100 V and 150 mA specifications.
