The 5310 pF input capacitance at 25 V drain bias sets the switching energy; expect miller-plateau duration around 50–80 ns with a 10 A gate driver, which is acceptable for hard-switched topologies up to about 150 kHz. ## Temperature range and deployment environment The 200 W maximum power dissipation at case temperature assumes an infinite heatsink — real designs must derate based on the thermal resistance of the D2PAK footprint on the PCB.","metaTitle":"IRF3808STRLPBF HEXFET N-Channel MOSFET, 75 V, 106 A, D2PAK","metaDescription":"IRF3808STRLPBF N-channel MOSFET from the HEXFET series. 75 V Vdss, 106 A continuous drain, 7 mOhm Rds(on) at 10 V.
