1N4148WS-HG3-18

Single Diodes Overview

The Vishay 1N4148WS-HG3-18 is a silicon epitaxial planar fast switching diode housed in an SOD-323 surface-mount package. It features a maximum repetitive peak reverse voltage of 100 V and a continuous average rectified forward current of 150 mA. The device exhibits a typical reverse recovery time of 4 ns, ensuring rapid switching performance. Electrical characteristics include a maximum forward voltage of 1.2 V at 100 mA and a leakage current of 100 µA at 100 V reverse bias. The component operates within a junction temperature range of -55 °C to +150 °C.

Single Diodes Feature Summary

• Utilizes silicon epitaxial planar technology for high-speed signal switching applications
• Complies with AEC-Q101 qualification standards for automotive reliability
• Manufactured using lead-free (HG3) materials adhering to green manufacturing specifications

Single Diodes Applications

• Automotive electronic circuits requiring qualified switching components
• High-frequency signal processing and logic level shifting
• General-purpose rectification in compact surface-mount designs

Single Diodes Procurement Notes

Verify the specific suffix '18' corresponds to the 10K per 13-inch reel packaging configuration as defined in the official datasheet parts table. Confirm that the HG3 designation aligns with required environmental compliance and automotive qualification standards for the intended application before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a small-form-factor SOD-323 footprint is required alongside strict automotive reliability standards. The 100 V rating provides adequate headroom for standard low-voltage digital logic systems. Ensure thermal management accounts for the specified junction-to-ambient resistance during high-duty-cycle operations.

Single Diodes Part Context

This part belongs to the 1N4148WS-G family of small signal fast switching diodes manufactured by Vishay General Semiconductor - Diodes Division. The HG3 variant specifically denotes the lead-free, environmentally compliant version that meets AEC-Q101 automotive qualification requirements, distinguishing it from commercial grade G3 counterparts.

Single Diodes Replacement Considerations

The 1N4148WS-G3-18 serves as the commercial-grade alternative within the same package and electrical specification profile. Verify that the absence of AEC-Q101 certification in the replacement part does not violate automotive system requirements.
