Input capacitance Ciss is 3200 pF at Vds = 25 V; this capacitance, together with the gate-drive source impedance, sets the turn-on and turn-off delay times and the cross-conduction window in a half-bridge topology. ## Thermal and environmental range Junction temperature range extends from -55°C to 175°C, qualifying the part for industrial and automotive environments where ambient heat and self-heating from high-current switching push the die temperature well above the board temperature. Maximum power dissipation is 300 W at the case temperature — the actual continuous dissipation in the application is derated by the junction-to-case thermal resistance and the board's ability to sink heat from the D²PAK tab.","metaTitle":"STB46NF30 N-Channel MOSFET, 300 V, 42 A, D2PAK","metaDescription":"STripFET™ II N-channel MOSFET, 300 V drain-source, 42 A continuous drain, 75 mOhm Rds(on) at 10 V.
