Total gate charge is 3.5 nC at 4.5 V. ## Package and thermal budget — the 3-PICOSTAR constraint The 3-XFDFN (3-PICOSTAR) package is a 3-pin, ultra-small surface-mount case. Maximum power dissipation is 1.4 W at 25°C ambient — that 5.3 A continuous rating assumes the PCB copper area is sized to keep the junction below 150°C. In a dense layout with limited copper, derate the continuous current; the part is better suited for pulsed or moderate-duty loads where the thermal time constant of the package averages the dissipation.","metaTitle":"CSD25485F5T P-Channel MOSFET, 20V, 5.3A, FemtoFET™","metaDescription":"Texas Instruments CSD25485F5T P-Channel MOSFET, 20V Vdss, 5.3A Id, 35mOhm Rds(on) at 8V.
