1N4148WGW

Single Diodes Overview

The Diotec Semiconductor 1N4148WGW is a small signal switching diode housed in an SOD-123 package. It features a maximum repetitive peak reverse voltage of 100 V and a maximum average forward current of 150 mA. The device exhibits a very high switching speed with a reverse recovery time under 4 ns. Forward voltage is specified at less than 0.855 V at 10 mA and less than 1.25 V at 100 mA. Junction capacitance is typically below 4 pF, and the component supports a junction temperature range from -55°C to +150°C.

Single Diodes Feature Summary

• Very high switching speed for fast signal processing
• Low junction capacitance and low leakage current
• Low profile plastic package design

Single Diodes Applications

• Signal processing circuits
• High-speed switching applications

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The standard version is commercial/industrial grade. Versions with suffixes -Q or -AQ are AEC-Q101 compliant or qualified respectively. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors before finalizing orders.

Single Diodes Selection Notes

Select this component for designs requiring compact surface-mount solutions with rapid switching capabilities. Ensure the application operates within the 150 mA average forward current limit and 100 V reverse voltage rating. Consider the -Q or -AQ variants if automotive qualification standards are required for the specific project environment.

Single Diodes Part Context

This part belongs to the 1N4148 family of small signal switching diodes produced by Diotec Semiconductor. It serves as the surface-mount equivalent to through-hole variants like the DO-35 packaged 1N4148. The SOD-123 form factor allows for automated assembly and space-constrained PCB layouts while maintaining comparable electrical performance to legacy axial components.

Single Diodes Replacement Considerations

Direct replacements include LL4148 (MiniMELF), MCL4148 (MicroMELF), and 1N4148WS (SOD-323). Verify pinout compatibility and thermal resistance differences when substituting these alternative case outlines.
