1N4448W-HE3_A-08

Single Diodes Overview

The Vishay 1N4448W-HE3_A-08 is a silicon epitaxial planar small signal fast switching diode housed in an SOD-123 surface-mount package. It features a maximum repetitive peak reverse voltage of 100 V and a continuous forward current rating of 300 mA. The device exhibits a typical reverse recovery time of 4 ns and a low junction-to-ambient thermal resistance of 440 K/W on an FR-4 board. It is qualified to AEC-Q101 standards for automotive applications.

Single Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability
• Fast switching capability with 4 ns reverse recovery time
• RoHS-compliant construction

Single Diodes Applications

• Automotive electronic circuits requiring high reliability
• General-purpose fast switching applications
• High-speed digital logic interface protection

Single Diodes Procurement Notes

Verify the specific HE3_A suffix confirms AEC-Q101 qualification status before procurement. Confirm the -08 packaging code corresponds to the required 3000 units per reel quantity. Ensure the design accommodates the SOD-123 footprint dimensions and soldering thermal profiles specified in the mechanical data section.

Single Diodes Selection Notes

Select this component when automotive-grade reliability is mandatory alongside fast switching performance. The SOD-123 package offers a compact solution for space-constrained designs. Compare against standard commercial grades if automotive qualification is not required, as the HE3_A variant specifically targets qualified environments.

Single Diodes Part Context

This part belongs to the 1N4448W series of small signal fast switching diodes manufactured by Vishay Semiconductors. The series includes both commercial (E3) and automotive (HE3_A) variants sharing identical electrical characteristics but differing in qualification standards. The SOD-123 case provides a standardized surface-mount form factor.

Single Diodes Replacement Considerations

Direct substitutes include other AEC-Q101 qualified 1N4448 equivalents in SOD-123 packages. Verify that replacement parts meet the 100 V RRM and 4 ns trr specifications. Cross-reference pinout and marking codes to ensure compatibility with existing assembly processes.
