Product Description

The AO3401A is an N-Channel 30V 4A MOSFET in a compact SOT-23 package, optimized for low-voltage switching applications. It features a maximum drain-source voltage of 30V, continuous drain current of 4A, and low on-resistance (RDS(ON)) for efficient power management. Designed for surface-mount configurations, it integrates seamlessly into circuits requiring high-speed switching, such as DC-DC converters, load switches, or battery protection systems. Operating within a temperature range of -55°C to 150°C, it is ideal for portable electronics, power supplies, and automotive modules. Key advantages include its small footprint, fast switching speed, and energy efficiency, though heat dissipation may require thermal management in high-current scenarios. Not applicable for screen or battery integration, it serves purely as a power-switching component.
