Gate charge totals 270 nC at 10 V — for a 100 kHz switching frequency the gate driver must supply 27 mA average to charge and discharge the gate, plus the peak current to overcome the Miller plateau. The ±20 V Vgs max gives margin for ringing on the gate node in a hard-switched motor-drive layout. ## Thermal and deployment context The TO-262 through-hole package bolts to a heatsink — the thermal resistance from junction to case determines the derating; at 175 °C junction the continuous current must be reduced per the datasheet curve.","metaTitle":"IRFSL7734PBF N-Channel MOSFET, 75 V, 3.5 mOhm, TO-262","metaDescription":"Infineon IRFSL7734PBF N-channel MOSFET, 75 V, 183 A switching, 3.5 mOhm Rds(on).
