BAT46WJ-QX

Single Diodes Overview

The BAT46WJ-QX is a planar Schottky barrier diode manufactured by Nexperia, featuring an integrated guard ring for enhanced stress protection. It is encapsulated in the SOD-323F (SC-90) surface-mount package. The device supports a maximum repetitive reverse voltage of 100 V and a continuous forward current of 250 mA. Key electrical characteristics include a low forward voltage of 850 mV at 250 mA and a peak reverse current of 600 μA. It operates within a temperature range of -55°C to +150°C and is qualified under the AEC-Q101 automotive standard.

Single Diodes Procurement Notes

Verify that the specific suffix '-QX' corresponds to the intended packaging configuration or variant requirements. Confirm AEC-Q101 qualification status aligns with target automotive application standards. Ensure compatibility with SOD-323F footprint specifications during PCB layout. Cross-reference datasheet parameters against system constraints before finalizing procurement decisions.

Single Diodes Selection Notes

Select this component for designs requiring robust reverse blocking capabilities up to 100 V in compact form factors. The low forward voltage drop aids in minimizing power dissipation during conduction. Consider the thermal management requirements given the 250 mA continuous current rating. Verify that the operating temperature range meets environmental conditions for the intended deployment scenario.

Single Diodes Part Context

This part belongs to the BAT46WJ series of Schottky diodes from Nexperia. It shares core electrical specifications with other variants in the family but may differ in packaging or qualification levels. The integration of a guard ring distinguishes it as a stress-protected device. It serves as a general-purpose rectifier solution for modern electronic systems requiring small footprints.

Single Diodes Replacement Considerations

Direct substitutes include BAT46WJ,115 and BAT46WH,115. Verify pinout compatibility and package dimensions when swapping between SOD-323F and SOD-123F variants. Ensure replacement parts meet the same AEC-Q101 automotive qualification if required by the design.
