1N4148WT

Single Diodes Overview

The YAGEO 1N4148WT is a silicon epitaxial planar switching diode housed in an SOD-523 surface-mount package. It features a maximum repetitive peak reverse voltage of 75 V and an average forward current rating of 125 mA. The device exhibits a fast switching characteristic with a maximum reverse recovery time of 4 ns. Electrical parameters include a maximum DC reverse voltage of 80 V, a forward voltage of 1.25 V at 50 mA, and a junction temperature range from -65 °C to 150 °C.

Single Diodes Feature Summary

• Fast switching capability with low reverse recovery time for high-frequency signal processing
• Compact SOD-523 surface-mount footprint designed for space-constrained circuit board layouts
• Silicon epitaxial planar construction ensuring stable performance across wide operating temperatures

Single Diodes Applications

• High-speed signal switching circuits
• Clamping and protection applications in consumer electronics
• General-purpose rectification in compact devices

Single Diodes Procurement Notes

Verify the manufacturer designation on component markings and datasheets, as the 1N4148WT form factor is widely produced by multiple semiconductor vendors. Confirm that the specific batch matches YAGEO specifications regarding pin configuration and electrical tolerances before integration into production designs.

Single Diodes Selection Notes

Select this component when a small surface-mount switching diode is required for general-purpose applications. Ensure the design accommodates the 125 mA average current limit and the 75 V reverse voltage rating. Verify thermal management requirements against the specified junction temperature limits during operation.

Single Diodes Part Context

This component belongs to the standard 1N4148 family of small-signal switching diodes. While traditional versions utilize through-hole DO-35 packages, the WT suffix indicates a modern surface-mount variant. This evolution allows for automated assembly and reduced board space usage while maintaining equivalent electrical characteristics to legacy discrete components.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' SOD-523 packaged 1N4148 variants such as Diotec 1N4148WT or Nexperia BAV99 equivalents if pinout compatibility is verified. Cross-reference absolute maximum ratings to ensure voltage and current margins are maintained.
