BAT54WS-HE3-18

Single Diodes Overview

The BAT54WS-HE3-18 is a small signal Schottky diode manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration in an SOD-323 (SC-76) surface-mount package. The device is rated for a maximum repetitive reverse voltage of 30 V and an average forward rectified current of 200 mA. It utilizes silicon technology and includes a PN junction guard ring for protection against excessive voltage stress, such as electrostatic discharges. The component is RoHS compliant and designed for high reliability applications.

Single Diodes Feature Summary

• Features very low turn-on voltage and fast switching characteristics
• Protected by a PN junction guard ring against excessive voltage and electrostatic discharges
• AEC-Q101 qualified for automotive applications
• RoHS-compliant commercial grade construction

Single Diodes Applications

• Automotive electronics requiring AEC-Q101 qualification
• High-reliability general-purpose rectification
• Low-voltage signal processing circuits

Single Diodes Procurement Notes

Verify the specific suffix HE3 indicates AEC-Q101 qualification and RoHS compliance as per official documentation. Confirm the SOD-323 package dimensions match design requirements. Ensure the manufacturer is identified as Vishay General Semiconductor - Diodes Division to distinguish from other series variants.

Single Diodes Selection Notes

Select this component when automotive qualification (AEC-Q101) is required alongside standard Schottky performance. The SOD-323 package offers space efficiency compared to larger through-hole options. Consider the 30 V reverse voltage rating for low-voltage DC applications where low forward voltage drop is critical.

Single Diodes Part Context

This part belongs to the BAT54W series of small signal Schottky diodes. The HE3 suffix denotes a specific manufacturing line that meets AEC-Q101 standards, distinguishing it from the standard E3 or G3 commercial grades within the same electrical specification family.

Single Diodes Replacement Considerations

BAT54WS-E3-18: Commercial grade equivalent without AEC-Q101 qualification. BAT54WS-G3-18: Alternative commercial grade variant. Verify package compatibility and qualification requirements before substitution.
