Input capacitance is 3700 pF at 25 V drain-source. ## 175 °C junction — the thermal budget for under-hood and industrial environments The 300 W power dissipation at the case is a theoretical ceiling — real-world dissipation is set by the D2PAK copper footprint on the PCB and the airflow. The part is ROHS3 compliant.","metaTitle":"STB85NF55T4 N-Channel MOSFET, 55 V, 80 A, D2PAK","metaDescription":"STB85NF55T4 STripFET™ II N-channel MOSFET, 55 V Vdss, 80 A Id, 8 mOhm Rds(on) at 10 V.
