Alpha & Omega Semiconductor Inc. AO3438 is an N-Channel enhancement mode MOSFET designed for demanding applications. This device features a 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. The AO3438 exhibits a low on-resistance (Rds On) of 62mOhm at 3A and 4.5V, and its gate threshold voltage (Vgs(th)) is 1V at 250µA. The device supports a wide gate drive voltage range, with minimum Rds On achieved at 4.5V. Key capacitance specifications include an input capacitance (Ciss) of 320pF at 10V and a gate charge (Qg) of 3.8nC at 4.5V. The AO3438 is housed in a compact SOT-23-3 package and is supplied on tape and reel. This MOSFET is suitable for use in power management, automotive, and industrial control systems.
