Overview
The STF28NM50N is a revolutionary N-channel Power MOSFET developed by STMicroelectronics using the second generation of MDmesh™ technology. This device combines a vertical structure with STMicroelectronics' strip layout, resulting in one of the world's lowest on-resistance and gate charge. This makes it highly suitable for the most demanding high-efficiency converters.
