A gate driver sourcing 1 A can turn it on in about 62 ns, but the 4680 pF input capacitance at 20 V drain-source means the driver sees a capacitive load that rises with Vds. The ±20 V gate-source maximum gives headroom for driving with a 12 V supply; the 4.5 V threshold for minimum Rds(on) lets it work from a 5 V logic rail if you accept higher on-resistance. ## Thermal endurance and environment The 175°C ceiling is common for automotive-grade power devices; the 2.1 V max gate threshold at 250 µA ensures it stays off at elevated temperatures where threshold voltage drifts downward.","metaTitle":"CSD18502KCS NexFET N-Channel MOSFET, 40 V, 100 A, TO-220-3","metaDescription":"CSD18502KCS NexFET N-channel MOSFET: 40 V Vdss, 100 A continuous, 2.9 mOhm Rds(on) at 10 V.
