Its headline figure is a maximum on-resistance of 4.7 mOhm at Vgs = 10 V and Id = 104 A — this sets the conduction loss in the steady-state on-period for a motor-drive or DC-DC converter output stage. With a gate charge of 230 nC at 10 V, the switching energy per transition depends on the gate-drive current available; a 2 A gate driver charges the gate in roughly 115 ns, though the actual switching loss in the application also includes the Miller plateau dwell time. ## Automotive temperature range and gate drive The junction temperature range spans -55 °C to 175 °C, covering under-hood and engine-bay thermal profiles where the ambient air can exceed 125 °C on a hot day with the engine running. The 175 °C max junction gives headroom for the self-heating from conduction and switching losses. The gate-source voltage is rated ±20 V absolute maximum — a 12 V or 15 V gate drive rail stays well within this, but a 24 V gate-drive supply would need a series clamp or zener to avoid exceeding the oxide stress limit. Maximum power dissipation is 330 W, though the practical limit in a real board depends on the heatsink and airflow; a TO-220 or similar through-hole package bolted to a 2 oz copper pad on a 4-layer board might handle 50-80 W continuous before the junction hits 175 °C.","metaTitle":"AUIRF2805 N-Channel HEXFET, 55V 75A, 4.7mOhm Rds(on)","metaDescription":"AUIRF2805 automotive N-channel HEXFET MOSFET. 55V drain, 75A continuous, 4.7mOhm Rds(on) at 10V.
