Alpha & Omega Semiconductor Inc. AO4494 is an N-Channel power MOSFET designed for high-efficiency switching applications. This component features a 30 V Drain-Source Voltage (Vdss) and a continuous Drain Current (Id) of 18 A at 25°C (Tc). The AO4494 exhibits a low on-resistance of 6.5 mOhm maximum at 18 A and 10 V, facilitated by a 4.5V to 10V drive voltage range. Its typical input capacitance (Ciss) is 1900 pF at 15 V, with a maximum Gate Charge (Qg) of 36 nC at 10 V. The MOSFET is packaged in an 8-SOIC (0.154"", 3.90mm Width) for surface mounting, with a maximum power dissipation of 3.1W (Ta). Operating over a temperature range of -55°C to 150°C (TJ), this device is suitable for use in power management, automotive, and industrial sectors. The AO4494 is supplied in Tape & Reel packaging.
