For a 100 kHz hard-switched application, the average gate-drive current required is 25.5 mA — within the capability of a standard totem-pole driver, but the peak current during the Miller plateau demands a driver with at least 2 A source/sink capability to keep switching losses under control. The ±20 V maximum gate-source rating provides margin for ringing on long gate traces in high-current layouts. ## Thermal and environmental rating Maximum power dissipation is 441 W at case temperature 25 °C, derated linearly above that point.","metaTitle":"IRF100B201 N-Channel MOSFET, 100 V, 192 A, TO-220AB","metaDescription":"IRF100B201 N-channel HEXFET MOSFET, 100 Vdss, 192 A continuous drain, 4.2 mOhm Rds(on) at 115 A.
