Product Description

The AO3442 MOSFET is a compact Power Transistor in an SOT23 package, designed for low-voltage, high-efficiency switching applications. This N-channel MOSFET features a 30V drain-source voltage rating with a continuous drain current of 5.7A and a pulsed current capability of 20A. It operates within a -55°C to 150°C temperature range, making it suitable for industrial power management, battery protection circuits, motor drivers, and DC-DC converters. The AO3442 SOT23 package offers a low on-resistance (16mΩ typical at 4.5V gate drive) and fast switching characteristics, enabling energy-efficient performance in space-constrained designs. While its small form factor optimizes PCB layout, thermal limitations may require heat management in high-current scenarios. The device includes three terminals (gate, drain, source) and lacks integrated communication interfaces, relying on standard MOSFET drive techniques. Key advantages include robust thermal stability, minimal power loss, and compatibility with automated assembly processes.
