1N4148WSGW

Single Diodes Overview

The Diotec Semiconductor 1N4148WSGW is a surface-mount small signal switching diode housed in an SOD-323 package. It features a maximum repetitive peak reverse voltage of 100 V and a DC reverse voltage rating of 75 V. The device supports a maximum average forward current of 150 mA and a non-repetitive peak forward surge current of 2.0 A for pulses up to 1 µs. Electrical characteristics include a forward voltage of less than 0.855 V at 10 mA, a reverse leakage current of less than 1 µA at 75 V, and a typical junction capacitance of 2 pF at 0 V. The component exhibits a reverse recovery time of less than 4 ns and operates within a junction temperature range of -55°C to +125°C.

Single Diodes Feature Summary

• Extremely fast switching speed with low junction capacitance
• Low leakage current under reverse bias conditions
• Compliant with RoHS directives without exemptions
• REACH regulation compliant and conflict minerals free

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific suffix requirements against project specifications. Confirm that the standard commercial/industrial grade meets reliability standards, as automotive grades require distinct -Q or -AQ suffixes. Ensure design parameters align with the specified thermal resistance and power dissipation limits on printed circuit boards with defined copper pad sizes.

Single Diodes Selection Notes

Select this component for general-purpose high-speed switching where low capacitance is critical. Evaluate the 150 mA average current limit against circuit load requirements. Consider the SOD-323 footprint constraints during layout. Verify compatibility with automated assembly processes given the taped and reeled packaging format.

Single Diodes Part Context

This part belongs to the Diotec 1N4148 series of small signal switching diodes. It shares functional similarities with other variants like the 1N4148WS but utilizes the SOD-323 case outline. The series provides alternatives across various packages including DO-35 and SOD-123F for different mounting needs.

Single Diodes Replacement Considerations

Direct substitutes include the 1N4148WS and 1N4148W from Diotec. Cross-manufacturer equivalents such as the BAV16W are functionally comparable. Verify pinout orientation and package dimensions before substitution.
