Single Diodes Procurement Notes

Verify the specific suffix QZ against official Nexperia documentation to confirm automotive qualification status and compliance requirements. Confirm availability status as production lifecycle data indicates potential obsolescence or discontinuation risks. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference RoHS directives and material declarations with the latest datasheet revision before finalizing procurement decisions.

Single Diodes Selection Notes

Select this component when a small form factor Schottky diode is required for low-voltage, high-speed signal paths. The DFN1110D-3 package offers thermal advantages over traditional plastic packages. Consider the 30 V reverse voltage limit and 200 mA current capability during circuit design. Evaluate the 800 mV forward voltage drop impact on system efficiency compared to lower Vf alternatives if power loss is critical.

Single Diodes Part Context

This device belongs to the BAT54 series of Schottky diodes from Nexperia, which are engineered for general-purpose high-speed switching. The series typically includes dual and triple configurations, but the BAT54QB variant specifies a single diode configuration. These components are widely used in consumer electronics and industrial control boards where space constraints and switching speed are primary design drivers.
