Introduction to the NVMFS5C682NLAFT1G N-Channel Power MOSFET

The NVMFS5C682NLAFT1G, manufactured by onsemi, is a single N-channel enhancement-mode power MOSFET optimized for demanding switching applications up to 60V. Packaged in a compact 5x6 mm DFN (8-SOFL), this device enables high-efficiency power solutions in automotive, industrial, and advanced consumer electronics sectors. With a maximum rated current of 8.8A (when mounted in free air at 25°C) and up to 25A with optimal heat sinking (case temperature), the NVMFS5C682NLAFT1G delivers exceptional versatility for space-constrained PCBs that require robust current handling and thermal management.

Primary Attributes and Application Advantages of NVMFS5C682NLAFT1G

The NVMFS5C682NLAFT1G integrates several features that address the performance and reliability needs of today’s switching architectures:

A low R_DS(on) value of approximately 21 mΩ reduces conduction losses, directly improving overall system efficiency and minimizing unnecessary power dissipation in compact, thermally-challenged environments.

The low gate charge (Q_G) and minimized capacitance allow faster switching speeds, helping achieve lower driver losses and supporting high-frequency operation. These traits are ideal for applications like DC-DC converters, synchronous rectification, and automotive switching nodes.

Its small footprint not only supports high-density PCB layouts but also streamlines system miniaturization without compromising electrical performance.

Available with a wettable flank option (NVMFS5C682NLWF) for automated optical inspection, simplifying high-volume production quality control and improving assembly yield.

The device is AEC-Q101 qualified and PPAP capable, ensuring reliability and traceability for automotive and other mission-critical applications.
