Alpha & Omega Semiconductor Inc. AO3494 is an N-Channel MOSFET designed for efficient power switching. This component features a maximum drain-source voltage (Vdss) of 20V and a continuous drain current (Id) of 3A at 25°C, with a maximum power dissipation of 1.4W (Ta). The AO3494 exhibits a low on-resistance (Rds On) of 62mOhm at 3A and 4.5V, supported by a gate threshold voltage (Vgs(th)) of 1V at 250µA. Drive voltages range from 1.8V to 4.5V, with a maximum gate-source voltage (Vgs) of ±8V. Key electrical characteristics include a maximum gate charge (Qg) of 10 nC at 4.5V and a maximum input capacitance (Ciss) of 260 pF at 10V. This device is supplied in a SOT-23-3 package for surface mounting and operates across an industrial temperature range of -55°C to 150°C (TJ). It is commonly utilized in consumer electronics, industrial control, and automotive applications. The AO3494 is delivered in Tape & Reel (TR) packaging.
