• Excellent coplanarity and improved thermal behavior

Applications

• Ultra high-speed switching circuits
• Voltage clamping applications
• Line termination tasks
• Reverse polarity protection

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm package type and automotive qualification status. Ensure the ordering code matches the required AEC-Q101 compliance level. Cross-reference the manufacturer's datasheet for exact mechanical dimensions and soldering recommendations before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a small SOT363-3 package. It is appropriate for designs needing low forward voltage and low capacitance characteristics. Consider its automotive qualification if the application operates in harsh environments requiring robust stress protection features.

Part Context

This part belongs to Nexperia's portfolio of Schottky barrier diodes. It utilizes planar technology to achieve fast switching speeds. The inclusion of a guard ring distinguishes it from standard variants by offering additional reliability under electrical stress conditions typical in modern electronic systems.

Replacement Considerations

Check for direct equivalents with identical pinout and electrical ratings. Verify that any substitute maintains the same AEC-Q101 qualification level and package footprint compatibility.
