Introduction to the NVMFS5C468NT1G onsemi MOSFET

The NVMFS5C468NT1G from onsemi is a single N-channel power MOSFET, optimized for high-efficiency operation in compact power circuits. Specified for a drain-source voltage of 40V and offering current capabilities up to 35A (Tc), this device combines a low RDS(on) of 12 mΩ and a robust surface-mount 5-DFN (5x6mm) package. It is suitable for rigorous automotive and industrial environments, featuring AEC-Q101 qualification and PPAP capability, ensuring reliability for demanding supply chains.

This MOSFET’s small footprint and advanced packaging allow engineers to reduce board space without sacrificing power handling, making the device particularly attractive for high-density designs requiring efficient switching and heat dissipation. The NVMFS5C468NT1G is also RoHS compliant and lead-free, aligning with modern environmental standards.

Typical Uses and Design Factors for NVMFS5C468NT1G onsemi

Engineers targeting efficient power conversion in automotive, industrial, and consumer applications will find the NVMFS5C468NT1G well suited to DC-DC converters, motor driver circuits, synchronous rectifiers, and high-side or low-side switching. The high maximum drain current (35A at case temperature) supports scenarios involving significant transient or continuous loads.

Real-world deployment involves considerations on pulse versus continuous currents, as the device specification notes higher current support for pulses up to one second, conditional on pulse duration and duty cycle. This property benefits designers implementing protection circuits or seeking dynamic load capability. The availability of the wettable flank DFN variant (NVMFS5C468NWF) further supports automated optical inspection processes, enhancing production yield through reliable solder joint visibility.
