Single Diodes Procurement Notes

Verify the specific suffix E3-18 against official Vishay documentation to confirm RoHS compliance and packaging configuration. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Cross-reference the manufacturer's latest datasheet for any design changes or obsolescence notices prior to final procurement decisions.

Single Diodes Selection Notes

Select this component when a 75 V reverse voltage rating and 150 mA current capacity are sufficient for the circuit requirements. The SOD-323 package is suitable for space-constrained PCB layouts. Consider the 4 ns reverse recovery time for applications demanding rapid switching speeds. Verify thermal management capabilities within the specified -55°C to 150°C junction temperature range.

Single Diodes Part Context

This part belongs to the 1N4148 family of small-signal switching diodes, adapted for surface-mount technology. The WS designation indicates the SOD-323 package variant. The E3 suffix denotes lead-free and RoHS compliance, while the -18 suffix typically specifies the reel size or packaging format according to manufacturer conventions.

Single Diodes Replacement Considerations

Compatible substitutes include 1N4148WS-G3-08 and 1N4148WS-HG3_A-08 from Vishay, which share similar electrical characteristics and package dimensions. Verify pinout compatibility and thermal performance before substitution.
