Input capacitance is 1110 pF at 25 V Vds — a figure that sets the driver's peak current requirement for the rise and fall edges. The ±20 V Vgs max gives headroom for gate ringing on long PCB traces. ## Thermal reality in the Micro6 package The 2 W power dissipation at 25°C ambient is the absolute limit in still air; derate aggressively above that temperature. The Micro6™ (TSOP-6) footprint has a small copper pad area under the drain tab — the datasheet's thermal resistance figure assumes a 1-inch-square pad on a 2-layer board. If your board is dense or the ambient runs to 85°C, budget for a lower continuous current than the 3.4 A headline number.","metaTitle":"IRF5803TRPBF HEXFET P-Ch MOSFET, 40V 3.4A, TSOP-6","metaDescription":"IRF5803TRPBF P-channel HEXFET MOSFET, 40V Vdss, 3.4A continuous drain, 112mOhm Rds(on) at 10V.
