With a total gate charge of 60 nC at 10 V, the driver must supply about 60 mA per MHz of switching frequency — a typical 100 kHz hard-switched stage draws roughly 6 mA from the driver, well within a standard gate-drive IC's capability. ## Thermal and environment rating The 125 W power dissipation rating assumes the TO-3 case is bolted to an adequate heatsink — the metal tab is the primary thermal path.","metaTitle":"IRF143 N-Channel MOSFET, 60 V, 24 A, TO-3 Package","metaDescription":"IRF143 N-Channel MOSFET, 60 V, 24 A, 110 mOhm Rds(on) at 10 V.
