Single Diodes Procurement Notes

Verify the specific suffix QYL against official Nexperia documentation to confirm packaging details and automotive qualification status. Ensure the ordering part number matches the required tape-and-reel specifications. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when low capacitance and fast switching speeds are critical. The XSON2 package offers a compact footprint compared to traditional SOT packages. Verify that the 30 V reverse voltage rating meets the circuit's peak inverse voltage requirements. Consider thermal dissipation limits if operating near the maximum forward current threshold.

Single Diodes Part Context

This device belongs to Nexperia's Schottky diode portfolio, which emphasizes low forward voltage and high efficiency. The LS suffix typically indicates specific packaging or automotive-grade variants within the series. These diodes are engineered for modern electronics requiring miniaturization and reliable performance in demanding environments.

Single Diodes Replacement Considerations

Check for direct substitutes such as the BAT42WJ or BAT46WJ from Nexperia, ensuring package compatibility and electrical parameter alignment. Verify that alternative components meet the same AEC-Q101 automotive qualification standards if required for the application.
