onsemi NVMFS5C628NLWFAFT1G: 100V Single N-Channel Power MOSFET Datasheet and Application Overview

The onsemi NVMFS5C628NLWFT1G is a state-of-the-art N-Channel Power MOSFET utilizing an advanced proprietary SuperFET III technology. This technology is engineered to deliver exceptional performance in power conversion and management applications, characterized by its low figure-of-merit (FOM) and high switching efficiency. Engineered in a compact, low-profile DFN5x6 package, this 100V MOSFET is an ideal solution for a wide range of modern, space-constrained, high-efficiency designs.

A primary strength of this MOSFET lies in its ultra-low on-resistance (RDS(on)), which is specified at a maximum of 6.2 mΩ at 10 V (VGS). This exceptionally low RDS(on) directly translates to minimized conduction losses, leading to higher system efficiency and reduced heat generation. This characteristic is paramount in applications where thermal management is a critical design challenge. The device is also optimized for fast switching performance, which helps to lower switching losses, especially in high-frequency circuits such as switch-mode power supplies (SMPS).

The robust 100V drain-to-source voltage (VDS) rating makes the NVMFS5C628NLWFT1G highly suitable for a broad spectrum of industrial and automotive applications. It provides a comfortable safety margin and reliable operation in 48V bus systems, telecom infrastructure, industrial motor drives, and DC-DC converters. Furthermore, the device is AQG-324 qualified, underscoring its reliability and suitability for demanding automotive environments, including engine control units, LED lighting, and battery management systems (BMS).

The DFN5x6 package offers significant advantages beyond its small footprint. Its exposed pad facilitates excellent thermal conductivity, allowing heat to be efficiently transferred from the silicon die to the PCB, thereby improving power dissipation and enabling higher current handling capabilities in a minimal space.

ICGOOODFIND: The onsemi NVMFS5C628NLWFT1G stands out as a superior component for designers seeking to maximize power efficiency and power density. Its combination of SuperFET III technology, ultra-low RDS(on), high voltage capability, and automotive-grade qualification makes it an exceptionally versatile and reliable choice for the most challenging power design tasks in industrial, telecom, and automotive sectors.
