Rated for a junction temperature up to 175°C, it is built for under-hood and engine-bay environments where ambient heat soaks the switching devices — think solenoid drivers, fuel-pump controllers, and DC motor bridges in 12 V truck or passenger-car systems. ## 60 mOhm at 11 A — the conduction-loss number that matters The on-resistance is specified at 60 mOhm maximum with Vgs = 10 V and Id = 11 A. That 11 A test point is the current level where the Rds(on) is characterised; the device is rated to switch 18 A continuously. For a 12 V automotive load at 10 A, the conduction loss at 60 mOhm is about 6 W — well within the 3.8 W power dissipation rating when the copper pad area on the PCB is sized correctly. ## Gate drive headroom: ±16 V Vgs for 12 V rails The gate-source voltage rating of ±16 V gives comfortable margin above a nominal 12 V gate drive. In an automotive environment where the battery rail can see load-dump transients up to 40 V, a gate driver with a 12 V regulated output keeps Vgs well inside the ±16 V limit. The gate charge is 15 nC at Vgs = 5 V, so a standard gate-driver IC can switch the FET at moderate PWM frequencies without excessive drive current.","metaTitle":"AUIRLZ24NS HEXFET N-Channel MOSFET, 55 V, 18 A, 60 mOhm","metaDescription":"AUIRLZ24NS automotive HEXFET N-channel MOSFET, 55 V, 18 A, 60 mOhm Rds(on) at 11 A.
