It is designed for high-current synchronous rectification in server VRMs, battery management systems, and DC-DC converters where minimizing conduction losses is critical for efficiency.","working_principle":"The NTMFS4C05N uses onsemi's latest trench MOSFET technology with optimized cell structure to achieve 3.2mOhm RDS(ON) in the compact Power33 package. The trench gate and stripe layout maximize channel density while minimizing gate charge (45nC total, 9nC switching). The Power33 package provides excellent thermal performance through its exposed die-attach pad, enabling the 118A current rating in a 3.3x3.3mm footprint.","pin_description":"
