1N4148W-HE3_A-08

Single Diodes Overview

The Vishay 1N4148W-HE3_A-08 is a silicon epitaxial planar fast switching diode housed in an SOD-123 surface-mount package. It features a repetitive peak reverse voltage of 100 V and a maximum reverse voltage of 75 V. The device supports a continuous forward current of 300 mA and an average rectified current of 250 mA, with a maximum reverse recovery time of 4 ns. Electrical characteristics include a forward voltage of up to 1.2 V at 100 mA and a leakage current of 100 µA at 100 V. It operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• Fast switching capability with a maximum reverse recovery time of 4 ns
• AEC-Q101 qualified for automotive reliability standards
• RoHS-compliant construction using UL 94 V-0 flammability rated molding compound

Single Diodes Applications

• High-speed signal processing circuits
• Automotive electronic systems requiring AEC-Q101 compliance
• General-purpose small-signal switching applications

Single Diodes Procurement Notes

Verify the HE3_A suffix confirms AEC-Q101 qualification status before procurement. Confirm the specific reel packaging code (08 or 18) matches the required tape width and quantity per reel. Ensure the component meets RoHS compliance requirements for the target assembly process.

Single Diodes Selection Notes

Select this component when automotive-grade reliability is mandatory alongside high-speed switching performance. The SOD-123 package provides a compact footprint suitable for space-constrained designs. Evaluate thermal resistance parameters against the expected ambient operating conditions to ensure safe power dissipation limits are not exceeded.

Single Diodes Part Context

This part belongs to the Vishay 1N4148W series of small signal fast switching diodes. It shares the same electrical specifications as the commercial grade 1N4148W-E3 variants but includes additional automotive qualification testing. The primary distinction lies in the manufacturing process and quality assurance protocols required for AEC-Q101 certification.

Single Diodes Replacement Considerations

The 1N4148W-E3-08 serves as the commercial equivalent without automotive qualification. Other manufacturers offer generic 1N4148 equivalents, though they may lack specific AEC-Q101 certification.
