Rds(on) is specified at 2.4 mOhm maximum with a 75 A drain current and 10 V gate drive — this is the conduction loss figure that sets the thermal budget for the heatsink. The 240 nC total gate charge at 10 V sets the gate drive current requirement for the target switching frequency. ## Thermal and environment envelope The 290 W power dissipation rating is the absolute maximum under ideal heatsinking; real-world continuous dissipation depends on the heatsink thermal resistance and airflow, so size the heatsink for the actual switching losses. ## Gate drive and threshold Gate threshold voltage is 4 V maximum at 250 µA drain current — this is the turn-on edge; a 10 V gate drive is recommended to fully enhance the channel and achieve the rated Rds(on). Maximum gate-source voltage is ±20 V.","metaTitle":"AUIRF2903Z N-Channel MOSFET, 30V, 160A, TO-220AB","metaDescription":"AUIRF2903Z N-Channel HEXFET MOSFET, 30V, 160A, Rds(on) 2.4mOhm at 75A.
