The Alpha & Omega Semiconductor Inc. AO3419L is a P-Channel, 20V trench MOSFET designed for efficient power switching. This component features a continuous drain current (Id) of 3.5A at 25°C and a maximum power dissipation of 1.4W. Its low on-resistance (Rds On) is specified at 75mOhm at 3.5A and 10V, with a gate-source threshold voltage (Vgs(th)) of 1.4V at 250µA. The AO3419L operates with a maximum gate-source voltage of ±12V and supports drive voltages from 2.5V to 10V. Key electrical characteristics include input capacitance (Ciss) of 620pF at 10V and gate charge (Qg) of 6.6nC at 4.5V. This device is housed in a compact SOT-23-3 (3-SMD, SOT-23-3 Variant) package, suitable for surface mounting, and is supplied in Tape & Reel (TR) packaging. It is engineered for applications in consumer electronics and automotive systems.
