BAT46WH-QX

Single Diodes Overview

The BAT46WH-QX is a single Schottky barrier diode manufactured by Nexperia. It features a planar structure with an integrated guard ring for stress protection, encapsulated in the SOD-123F surface-mount package. Key electrical parameters include a maximum reverse voltage of 100 V and an average forward current of 250 mA. The device exhibits a low forward voltage drop of 850 mV at 250 mA and a peak non-repetitive forward surge current capability of 2.5 A.

Single Diodes Feature Summary

• Single planar Schottky barrier diode design with integrated guard ring for enhanced stress protection
• Low forward voltage characteristic suitable for efficient power conversion
• Small and flat lead SOD-123F plastic package for compact surface-mount applications

Single Diodes Applications

• High-speed switching circuits
• Line termination
• Voltage clamping
• Reverse polarity protection

Single Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm automotive qualification status (AEC-Q101) and packaging format. Ensure the selected variant matches the required tape-and-reel quantity and moisture sensitivity level for your assembly process. Cross-reference the part number with the manufacturer's latest longevity program data to confirm availability and expected order duration.

Single Diodes Selection Notes

Select this component when a low-capacitance, high-speed rectifier is needed in a small footprint. The SOD-123F package offers a balance between current handling and board space efficiency. Consider the 100 V reverse voltage rating for general-purpose applications where moderate blocking voltage is sufficient. Verify thermal management requirements based on the 400 mW power dissipation limit if operating near maximum current.

Single Diodes Part Context

This device belongs to the BAT46 series of Schottky diodes from Nexperia. It shares functional similarities with other members like the BAT46WJ but differs in package type, utilizing the SOD-123F form factor instead of SOD-323. The series is designed for applications requiring fast switching speeds and low forward voltage drops in consumer and industrial electronics.

Single Diodes Replacement Considerations

Direct replacements must match the SOD-123F package and 100 V / 250 mA ratings. Check datasheets for equivalent parts from other manufacturers to ensure compatibility with forward voltage and reverse leakage specifications.
