The 34 nC total gate charge at 10 V is moderate for a 500 V / 14 A device; a gate driver delivering 1 A can switch the FET in roughly 34 ns, keeping crossover losses manageable in the 50–150 kHz range typical of hard-switched converters. Input capacitance Ciss is 1000 pF at Vds = 50 V, which sets the gate-drive impedance requirement for clean edges without ringing. The TO-220FP (TO-220 Full Pack) has a fully moulded plastic body with no exposed metal tab — the back of the package is the heatsink face, electrically isolated. Maximum power dissipation is 30 W at case temperature, limited by the junction-to-case thermal resistance of the full-pack construction. For a typical 100 W PFC stage running at 70°C ambient, the designer should verify the junction temperature stays below the 150°C TJ rating.","metaTitle":"STF19NM50N N-Channel MOSFET, 500V, 14A, TO-220FP","metaDescription":"STF19NM50N MDmesh II N-Channel MOSFET: 500V Vdss, 14A Id, 250mOhm Rds(on) at 10V.
