The TO-220FP full-pack package isolates the tab electrically, so no insulating pad or washer is needed against the heatsink — a BOM simplification for single-ended designs. ## 99 mOhm Rds(on) and 56.5 nC gate charge — sizing the drive and the heatsink At 10 A load, expect roughly 9.9 W conduction loss at 25 °C junction; the 25 W package dissipation limit means the designer must derate for ambient temperature and switching losses.","metaTitle":"STF40N65M2 N-Channel MOSFET, 650 V, 32 A, MDmesh M2","metaDescription":"STF40N65M2 N-channel 650 V 32 A MOSFET in TO-220FP. 99 mOhm Rds(on) at 10 V, 56.5 nC gate charge.
