The 1.28 Ohm maximum on-resistance at 2.8 A and 10 V gate drive sets the conduction loss floor — at full rated current the dissipation in the channel alone is roughly 39 W, which exceeds the 30 W package limit, so real-world operation derates the current or requires a heatsink that keeps the junction below 150°C. The through-hole TO-220FP full-pack package isolates the metal tab from the drain, so the device can be bolted directly to a chassis or heatsink without an insulating pad — a time-saver on the assembly line and one less thermal interface to model. The 30 W maximum power dissipation at case temperature is the thermal budget to work with; a 50°C ambient with a 1°C/W heatsink leaves about 70°C junction rise, which is comfortable for continuous 2 A loads. ## Gate drive and switching profile Gate charge is 34 nC at 10 V gate drive — a manageable figure for a discrete driver or a PWM controller's totem-pole output. At a 50 kHz switching frequency the average gate-drive current is 1.7 mA, well within the capability of most gate-drive ICs. The 875 pF input capacitance at 50 V drain bias means the driver sees a capacitive load that rises with the Miller plateau; the total switching loss depends on how fast the driver can push that 34 nC in and out. The 4.5 V gate threshold at 50 µA drain current is a typical SuperMESH3 figure — the device is fully enhanced at 10 V drive (the specified Rds(on) condition) but will start conducting well below that. For logic-level drive at 5 V the on-resistance will be higher than the 1.28 Ohm datasheet value, so factor that into the conduction loss calculation if the gate drive rail is not 10 V. ## Lifecycle and compliance The base product number is STF6, covering the TO-220FP family in this voltage and current class. The part is supplied in Tube packaging — 50 pieces per tube typical for TO-220, though the exact quantity per tube should be confirmed with the distributor at order time.","metaTitle":"STF6N62K3 N-Ch MOSFET, 620 V, 5.5 A, TO-220FP","metaDescription":"STMicroelectronics STF6N62K3 N-channel MOSFET, 620 Vdss, 5.5 A Id, 1.28 Ohm Rds(on), SuperMESH3 series, TO-220FP.
