This device is realized with the second generation
of MDmesh™ technology. This revolutionary
Power MOSFET associates a new vertical
structure to the company’s strip layout to yield one
of the world’s lowest on-resistance and gate
charge. It is therefore suitable for the most
demanding high efficiency converters
