BAT46W-HE3-08

Single Diodes Overview

The BAT46W-HE3-08 is a small signal Schottky diode manufactured by Vishay Semiconductors. It features a repetitive peak reverse voltage of 100 V and an average forward rectified current of 150 mA. The device exhibits a maximum forward voltage drop of 1 V at 250 mA. It is housed in the SOD-123 surface-mount package, measuring 3.85 mm in length, 1.7 mm in width, and 1.35 mm in height. The component operates within a junction temperature range of -55 °C to +150 °C and holds AEC-Q101 qualification for automotive reliability.

Single Diodes Feature Summary

• Features very low turn-on voltage and fast switching characteristics suitable for general-purpose applications
• Protected by a PN junction guard ring against excessive voltage stress such as electrostatic discharges
• Qualified under AEC-Q101 standards for automotive electronic component reliability

Single Diodes Applications

• General purpose rectification circuits
• Automotive electronics systems requiring AEC-Q101 compliance
• Clamping and protection applications utilizing the internal guard ring

Single Diodes Procurement Notes

Verify the specific HE3 suffix indicates RoHS compliance and AEC-Q101 qualification status according to the manufacturer's official datasheet. Confirm the SOD-123 mechanical dimensions match your PCB footprint requirements. Ensure the 100 V reverse voltage rating meets your circuit's peak inverse voltage demands. Check for any recent product change notices regarding packaging or material composition updates from Vishay.

Single Diodes Selection Notes

Select this component when a compact surface-mount Schottky diode with automotive qualification is required. The SOD-123 package offers space efficiency compared to larger through-hole alternatives. Consider the 150 mA current limit for low-power signal processing tasks. The low forward voltage drop contributes to improved system efficiency in sensitive power paths.

Single Diodes Part Context

This part belongs to the BAT46W series of small signal Schottky diodes produced by Vishay Semiconductors. The series is designed for high-speed switching and low-loss rectification in compact form factors. The HE3 designation specifically denotes RoHS-compliant materials with enhanced automotive-grade testing protocols defined by the AEC-Q101 standard.

Single Diodes Replacement Considerations

BAT46W-E3-08 serves as a commercial grade alternative lacking AEC-Q101 qualification. BAT46W-G3-08 represents another RoHS-compliant variant within the same family. Verify that substitute parts maintain identical SOD-123 mechanical dimensions and electrical ratings before implementation.
