Gate charge totals 55 nC at 10 V, so the driver must supply roughly 5.5 mA per 100 kHz of switching frequency just to charge the gate capacitance; the actual switching loss scales with the Qg × Vgs × fsw product. ## Gate threshold and drive voltage Input capacitance is 1180 pF typical at 25 V drain-source, which together with the gate charge sets the switching speed ceiling; the Miller plateau region is where the gate driver spends most of its time during the switching transition. ROHS3 compliant per the manufacturer's declaration, with no lead, mercury, cadmium, or restricted phthalates in the package materials.","metaTitle":"STB30NF10T4 N-Channel MOSFET, 100V 35A D2PAK","metaDescription":"STB30NF10T4 N-channel MOSFET, 100V Vdss, 35A Id, 45mOhm Rds(on) at 15A/10V.
