1N4148W-HE3-08

Single Diodes Overview

The Vishay 1N4148W-HE3-08 is a standard switching diode in the SOD-123 surface-mount package. It features a maximum DC reverse voltage (Vr) of 75 V and an average forward rectified current (Io) of 150 mA. The device exhibits a peak reverse recovery time (trr) of 4 ns and a maximum forward voltage (Vf) of 1.2 V at 100 mA. Reverse leakage current is specified as 100 µA at 100 V, with junction capacitance of 4 pF at 0 V bias. Operating temperature ranges from -55°C to +150°C.

Single Diodes Feature Summary

• High-speed switching capability with 4 ns reverse recovery time
• Automotive-grade reliability certified to AEC-Q101 standards
• Lead-free construction compliant with RoHS directives

Single Diodes Applications

• General-purpose signal switching circuits
• Automotive electronic systems requiring AEC-Q101 compliance
• High-frequency rectification applications

Single Diodes Procurement Notes

Verify the specific suffix HE3-08 against official Vishay documentation to confirm lead-free status and packaging configuration. Ensure the ordering part number matches the required tape-and-reel or cut-tape format for your assembly line. Cross-reference the datasheet revision date to confirm the latest electrical characteristics and mechanical dimensions are applied.

Single Diodes Selection Notes

Select this component when high-speed switching performance is required in a compact SOD-123 footprint. The AEC-Q101 qualification makes it suitable for automotive environments where thermal stability up to 150°C is necessary. Compare the 150 mA current rating against circuit load requirements to ensure adequate margin for peak currents.

Single Diodes Part Context

This part belongs to the 1N4148 family of small-signal switching diodes manufactured by Vishay General Semiconductor. It serves as a modern surface-mount alternative to traditional axial-lead packages, offering similar electrical performance in a smaller form factor suitable for dense PCB layouts.

Single Diodes Replacement Considerations

Compatible substitutes include the 1N4148WS-G3-08 (SOD-323 package) and other 1N4148 variants in SOD-123 or SOD-323 packages from Vishay, provided they meet the same 75V/150mA specifications and AEC-Q101 requirements.
