- Switching applications **Figure 1: Internal schematic diagram** ## **Description** This device is an N-channel Power MOSFET developed using the second generation of MDmesh™ technology. This revolutionary Power MOSFET associates a 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. **Table 1: Device summary** |**Order code**|**Marking**|**Package**|**Packaging**| |---|---|---|---| |STF11NM50N|11NM50N|TO-220FP|Tube| June 2016 DocID028675 Rev 2 1/13 This is information on a product in full production. _www.st.com_ |**Contents**
