1N4148WS

Single Diodes Overview

The Diotec Semiconductor 1N4148WS is a small signal switching diode housed in an SOD-323F surface-mount package. It features a maximum average forward current of 150 mA and a repetitive peak reverse voltage of 100 V, with a DC reverse voltage rating of 75 V. The device exhibits a reverse recovery time of less than 4 ns and a typical junction capacitance of 2 pF at 0 V and 1 MHz. Forward voltage is specified as less than 0.855 V at 10 mA and 1.25 V at 150 mA. Leakage current is under 1 µA at 75 V and 25°C. Operating temperatures range from -55°C to +150°C.

Single Diodes Feature Summary

• Extremely fast switching speed suitable for high-frequency applications
• Low junction capacitance for minimal signal distortion
• Low leakage current ensuring efficient blocking performance
• Compliant with RoHS directives without exemptions

Single Diodes Applications

• Signal processing circuits
• High-speed switching applications
• Commercial and industrial grade electronics

Single Diodes Procurement Notes

Verify the specific suffix when ordering. The base part number denotes standard commercial or industrial grade components. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ indicates AEC-Q101 qualification. Confirm these designations match project reliability requirements before procurement.

Single Diodes Selection Notes

Select this component for designs requiring compact surface-mount solutions with rapid switching capabilities. Ensure the circuit operates within the 150 mA average forward current limit. Verify thermal management aligns with the specified junction temperature range of -55°C to +150°C for the intended environment.

Single Diodes Part Context

This component belongs to the 1N4148 family of silicon switching diodes. It serves as a surface-mount alternative to through-hole variants like the DO-35 packaged 1N4148. The SOD-323F case provides a smaller footprint compared to larger packages while maintaining similar electrical characteristics for general-purpose signal handling.

Single Diodes Replacement Considerations

Diotec lists 1N4448WS as an alternative within the same product line. Other manufacturers offer equivalents in SOD-323 or SOD-123F packages. Verify pinout compatibility and ensure replacement parts meet the required AEC-Q101 standards if automotive reliability is necessary.
