1N4151W-HE3_A-18

Single Diodes Overview

The Vishay 1N4151W-HE3_A-18 is a silicon epitaxial planar small signal fast switching diode housed in an SOD-123 surface-mount package. It features a maximum reverse voltage of 50 V and an average rectified forward current of 250 mA. The device offers a typical reverse recovery time of 4 ns at 10 mA conditions, with a maximum leakage current of 50 nA at 50 V. It operates within a junction temperature range of -55 °C to +150 °C and is AEC-Q101 qualified for automotive reliability.

Single Diodes Feature Summary

• Fast switching capability with low reverse recovery time
• Automotive grade qualification under AEC-Q101 standards
• RoHS-compliant construction using UL 94 V-0 flammability rated molding compound

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific HE3_A suffix confirms AEC-Q101 automotive qualification status before integration. Confirm the -18 packaging code corresponds to the required reel specifications for automated assembly lines. Ensure design validation accounts for the specified thermal resistance values under actual operating conditions.

Single Diodes Selection Notes

Select this component when high-speed switching performance is critical alongside automotive reliability requirements. The SOD-123 package provides a compact footprint suitable for space-constrained designs. Compare against standard commercial grades if automotive certification is not mandatory for the target application environment.

Single Diodes Part Context

This part belongs to the 1N4151W series of small signal fast switching diodes manufactured by Vishay Semiconductors. The series utilizes silicon epitaxial planar technology to deliver consistent switching characteristics across various operating temperatures and voltage conditions.

Single Diodes Replacement Considerations

The 1N4151W-E3-18 serves as a commercial grade alternative lacking AEC-Q101 qualification. Verify that substituting non-automotive versions meets all system reliability standards.
