BAT754L-QX

Overview

The BAT754L-QX is a Schottky barrier triple diode manufactured by Nexperia. It contains three internal isolated planar Schottky barrier diodes with an integrated guard ring for stress protection, encapsulated in a very small SOT363-3 (SC-88) Surface-Mounted Device plastic package. The device features low forward voltage and low capacitance characteristics. It is qualified under the AEC-Q101 standard for automotive applications. Key electrical parameters include a maximum continuous forward current of 200 mA, a peak reverse repetitive voltage of 30 V, and a peak non-repetitive forward surge current of 600 mA. The operating temperature range spans from -55°C to +150°C.

Procurement Notes

Verify the specific suffix 'QX' against the official Nexperia datasheet to confirm it denotes the reel packaging format and AEC-Q101 qualification status. Ensure the ordering part number matches the exact component marking required for your bill of materials. Confirm availability through authorized distributors as supply levels may vary. Check for any recent Product Change Notifications that might affect pinout or material composition before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple independent Schottky diodes in a minimal footprint. The AEC-Q101 qualification makes it suitable for automotive electronics where reliability is critical. Consider its low forward voltage for efficiency in low-voltage signal paths. Verify that the 30V reverse voltage rating meets the circuit's peak inverse voltage requirements. The SOT363-3 package is ideal for space-constrained PCB layouts.

Part Context

The BAT754L-QX belongs to Nexperia's portfolio of Schottky barrier triple diodes. It is part of the broader BAT754 series, which offers compact solutions for signal processing and power management. The QX suffix typically indicates automotive-grade qualification and specific packaging. This component leverages Nexperia's expertise in small-scale, high-density circuit designs, providing engineers with robust protection and switching capabilities in a miniature surface-mount package.

Replacement Considerations

Check for other BAT754 variants with different suffixes that may offer identical electrical performance but different packaging or qualification levels. Ensure any substitute maintains the SOT363-3 footprint and AEC-Q101 compliance if automotive use is intended. Verify that the replacement part has matching forward voltage and reverse leakage specifications to avoid circuit performance degradation.
