Gate charge is 39 nC at 10 V, and input capacitance is 940 pF at 25 V drain bias — this combination means a modest gate-driver output stage (1 A to 2 A peak) can switch the device in the tens-of-kilohertz range without excessive crossover loss. ## Obsolete — the sourcing reality for STP20N20","metaTitle":"STP20N20 N-Channel MOSFET, 200 V, 18 A, TO-220, Obsolete","metaDescription":"STP20N20 N-Channel MOSFET from STMicroelectronics STripFET™ II series. 200 Vdss, 18 A continuous drain, 125 mOhm Rds(on) at 10 V.
