Gate charge and switching speed
The IRF1018ESTRLPBF: Total gate charge is 69 nC at 10 V. The 2290 pF input capacitance at 50 V Vds charges each cycle.
Package and thermal path
The 110 W maximum power dissipation at 25 °C case temperature assumes the tab is held at that temperature — real-world derating depends on the board's copper thickness and airflow. The -55 °C to 175 °C junction range covers automotive under-hood and industrial motor-drive environments.
