SiNESEMI specifically recommends its industry-leading SMT4005 series automotive-grade MOSFETs, which are designed to meet the requirements for miniaturization, compactness, and high efficiency in automotive water pump applications.
Dual-channel automotive-grade MOSFETs such as the SMT4005AHPDQ, along with other automotive-grade products in this series, have passed the rigorous AEC-Q101 certification by SGS—the world’s top inspection agency in the testing and certification field. They have also gained recognition from global customers for their efficient PPAP support.
Compared with benchmark products from major European and American manufacturers, the SMT4005 series offers approximately 10% lower on-state impedance and a roughly 15% improvement in Figure of Merit (FOM) value. This translates to higher efficiency, lower power consumption, and reduced temperature rise. Additionally, an enhanced withstand voltage margin and chip-level safety redundancy design further boost the safety factor of these devices.
In practical application circuits, this (referring to SiNESEMI’s MOSFET solution) results in a significant reduction in the system’s overall power loss—making it highly suitable for low-power (below 150W) three-phase BLDC (Brushless DC) motor applications in automobiles, such as water pumps, oil pumps, car windows, sunroofs, and tailgates. The SMT4005AHP(D)Q has already been shipped in bulk to automotive end customers.
