The 14240 pF input capacitance at 25 V drain-source reinforces the same point: this is a large-die part built for low ohmic loss, not fast edge rates. Plan for a dedicated gate-driver IC, not a logic-level output. ## Thermal and temperature range Junction temperature spans -55°C to 175°C, which covers automotive under-hood and industrial motor-drive environments. The 375 W maximum power dissipation at case temperature is a theoretical ceiling — real-world dissipation depends on the heatsink and airflow. The D2PAK (TO-263) surface-mount package with the exposed tab carries the heat into the PCB copper pour.","metaTitle":"IRFS7430TRLPBF N-Channel MOSFET, 40V, 195A, 1.2mOhm D2PAK","metaDescription":"IRFS7430TRLPBF N-Channel HEXFET MOSFET, 40V, 195A, 1.2mOhm Rds(on) at 10V.
