The 300 W power dissipation at case temperature is the thermal budget ceiling; the actual dissipation depends on the heatsink's thermal resistance.","metaTitle":"IRF3805PBF HEXFET N-Channel MOSFET, 55V 75A TO-220AB","metaDescription":"IRF3805PBF N-channel HEXFET MOSFET, 55V Vdss, 75A continuous drain, 3.3 mOhm Rds(on) at 10V.
