1N4148WT-76K

Single Diodes Overview

The 1N4148WT-76K is a small signal switching diode manufactured by Diodes Incorporated. It features a single diode configuration in an SOD-523 surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 80 V, a forward current of 125 mA to 250 mA depending on specific rating conditions, and a maximum reverse recovery time of 4 ns. The device operates within a temperature range of -55 °C to +150 °C junction temperature.

Single Diodes Feature Summary

• Fast switching capability with low reverse recovery time for high-speed digital applications
• Compact SOD-523 plastic surface-mount package for space-constrained designs
• High thermal stability supporting operation up to 150 °C junction temperature

Single Diodes Applications

• General purpose switching circuits
• Digital logic interface protection
• Clamping and clamping diodes in signal processing

Single Diodes Procurement Notes

Verify the exact forward current rating (125 mA vs 250 mA) and reverse voltage specifications against the official Diodes Incorporated datasheet for part number 1N4148WT-76K. Ensure the SOD-523 package dimensions and moisture sensitivity level requirements align with your assembly process standards before finalizing procurement.

Single Diodes Selection Notes

Select this component when a compact, fast-switching silicon diode is required for low-power signal handling. The SOD-523 package offers a smaller footprint compared to traditional axial leads. Confirm that the 80 V reverse voltage rating meets the circuit's peak inverse voltage requirements and that the 4 ns recovery time satisfies the system's speed constraints.

Single Diodes Part Context

This component belongs to the standard 1N4148 family of small signal switching diodes. While the base 1N4148 typically refers to the DO-35 axial package, the WT suffix indicates the SOD-523 surface-mount variant. Diodes Incorporated produces this specific version to provide equivalent electrical performance in a modern surface-mount form factor suitable for automated PCB assembly.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4148 variants in SOD-523 packages, such as ON Semiconductor's 1N4148W or Vishay's 1N4148WS. Verify pinout compatibility and ensure the substitute meets the same 80 V reverse voltage and 4 ns reverse recovery time specifications.
