Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against the manufacturer's latest datasheet before procurement. Confirm that the component meets the required AEC-Q101 automotive grade specifications for the target application environment. Ensure compatibility with standard surface-mount assembly processes for the SO-8FL package type.

Selection Notes

Select this component when a dual N-channel MOSFET with low on-resistance and high current capability is required in a small footprint. Consider the 40 V rating and 44 A current capacity relative to the system's voltage and load requirements. Evaluate thermal management needs based on the 27 W power dissipation rating and the specific PCB copper area available for heat sinking.

Part Context

This part belongs to the NVMFD5 series of dual MOSFETs from onsemi, designed for space-constrained power applications. The series typically offers integrated solutions for half-bridge or synchronous rectifier configurations. The NVMFD5852NLWFT1G variant specifically targets 40 V systems requiring high efficiency and robust automotive-grade performance.

Replacement Considerations

Direct replacements must match the 40 V, dual N-channel specification with similar Rds(on) and current ratings. Verify pinout compatibility with the SO-8FL-Dual-8 package. Check if alternative parts meet the same AEC-Q101 automotive qualification standards.
