Alpha & Omega Semiconductor Inc. AO3401 is a P-Channel enhancement mode MOSFET designed for efficient power switching applications. This component features a drain-source breakdown voltage (Vdss) of 30V and can handle a continuous drain current (Id) of 4A at 25°C, with a maximum power dissipation of 1.4W (Ta). The AO3401 exhibits a low on-resistance (Rds On) of 50mOhm at 4A and 10V Vgs, supported by a gate-source threshold voltage (Vgs(th)) of 1.3V at 250µA. Typical applications include power management, battery protection circuits, and load switching in consumer electronics and industrial control systems. The device is packaged in a compact SOT-23-3 (3-SMD, SOT-23-3 Variant) and supplied on tape and reel. Key electrical characteristics include a gate charge (Qg) of 14 nC (max) at 10V and input capacitance (Ciss) of 645 pF (max) at 15V. The operating temperature range is -55°C to 150°C (TJ).
