Total gate charge is 29 nC at 10 V, and input capacitance measures 1635 pF at 300 V drain bias. For a 100 kHz hard-switched converter, the gate driver must supply an average current of about 2.9 mA just to charge the gate — well within a standard 1 A driver, but the peak current at turn-on is set by the driver's source impedance and the gate resistance. The 29 nC figure also lets you estimate switching losses: each transition dissipates roughly 0.5 × Vds × Id × (tr + tf), and the gate charge determines how fast the Miller plateau is traversed. ## TO-220 package — thermal and mechanical fit The through-hole TO-220-3 package (supplier device package TO-220) dissipates up to 150 W at the case, but the real thermal limit depends on the heatsink and mounting torque. The 150 W figure is the absolute-maximum rating at Tc=25 °C; derate linearly above that case temperature per the datasheet's thermal resistance curve.","metaTitle":"TK155E65Z,S1X Toshiba N-Ch MOSFET, 650V 18A TO-220","metaDescription":"TK155E65Z,S1X Toshiba N-Channel MOSFET, 650V Vdss, 18A Id, 155mOhm Rds(on).
