Input capacitance is 1800 pF at 20 V Vds — the Miller plateau is short, so the switching losses stay modest in hard-switched topologies like synchronous buck converters or motor H-bridges. ## Current rating and thermal headroom Continuous drain current is rated 53 A at 25 °C ambient (Ta) and 100 A at 25 °C case (Tc). The 100 A figure assumes the case is held at 25 °C — in practice the tab must be bolted to a heatsink with thermal compound. It is ROHS3 compliant.","metaTitle":"CSD18504KCS NexFET N-Ch MOSFET, 40V, 7mOhm at 10V","metaDescription":"TI CSD18504KCS NexFET N-channel MOSFET, 40V Vds, 7mOhm Rds(on) at 10V, 100A continuous.
