Low RDS(on) and High Current Capability for Next‑Generation Power Designs

Micro Commercial Components (MCC) introduces the MCGXDXN04YX series, a family of highefficiency 40V NChannel MOSFETs designed to meet the growing demand for compact, highperformance power solutions. Power systems today are increasingly constrained by board space while requiring higher current capability and improved efficiency, creating challenges in thermal management and switching performance.

The MCGXDXN04YX series, available in the compact PDFN3333 package, addresses these challenges by combining ultralow RDS(on) values of 4.5mΩ, 5.8mΩ, and 8.2mΩ with continuous drain current capability up to 80A. Built on Split Gate Trench (SGT) MOSFET technology, these devices reduce switching losses while maintaining excellent thermal performance. With logiclevel gate drive compatibility and optimized characteristics, the series delivers reliable, highefficiency operation across a wide range of power applications
