The three-lead body is the standard high-power footprint for offline converters, PFC stages, and motor-drive inverters where the thermal path runs through the tab to a heatsink. ## 119 nC gate charge — drive current at switching frequency Total gate charge is 119 nC at 10 V. Input capacitance is 2600 pF at 25 V drain-source, which sets the driver's dynamic load during the turn-on ramp.","metaTitle":"STW20NK50Z N-Ch MOSFET 500V 17A TO-247-3","metaDescription":"STMicroelectronics STW20NK50Z SuperMESH N-channel MOSFET, 500V Vdss, 17A Id, 270mOhm Rds(on).
