1N4148W-7

Single Diodes Overview

The 1N4148W-7 is a surface-mount fast switching diode manufactured by Diodes Incorporated in the SOD-123 package. It features a peak repetitive reverse voltage of 100 V and a forward continuous current rating of 300 mA. The device exhibits a maximum reverse recovery time of 4 ns and a total capacitance of 2 pF at 0 V bias. Forward voltage ranges from 0.715 V to 1.25 V depending on current levels up to 150 mA. Power dissipation is rated at 400 mW with a thermal resistance of 315 °C/W. Operating temperature spans -55°C to +150°C.

Single Diodes Feature Summary

• Fast switching speed with low reverse recovery time
• Low forward voltage drop for efficient conduction
• Surface-mount package optimized for automated insertion
• Lead-free, halogen-free, and antimony-free construction

Single Diodes Applications

• General purpose switching applications
• Automotive electronics requiring specific change control (via 1N4148WQ variant)
• High reliability circuits utilizing AEC-Q101 qualified components

Single Diodes Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm packaging quantity and compliance status. The standard tape and reel configuration typically contains 3,000 units per carrier. Confirm that the selected part number matches the required RoHS and environmental specifications for your assembly process. Cross-reference the date code marking system to ensure production year alignment with project timelines.

Single Diodes Selection Notes

Select this component when high-speed signal switching is required within a compact surface-mount footprint. The SOD-123 case provides an ideal balance between current handling capability and board space efficiency. Ensure the application voltage does not exceed the 100 V peak repetitive reverse rating. Consider the 1N4148WQ variant if automotive qualification and PPAP capabilities are mandatory for the design.

Single Diodes Part Context

This device belongs to the BAV16W/1N4148W series of surface-mount fast switching diodes produced by Diodes Incorporated. It serves as a modern replacement for through-hole equivalents like the DO-35 packaged 1N4148, offering improved automation compatibility. The series includes variants such as the BAV16W and the automotive-grade 1N4148WQ, all sharing similar electrical characteristics but differing in qualification standards.

Single Diodes Replacement Considerations

Direct substitutes include the BAV16W-7-F and the automotive-qualified 1N4148WQ-7-F from the same manufacturer family.
