AO3400 Logic-Level MOSFET

The AO3400 is a single N-Channel Logic Level MOSFET from Alpha & Omega Semiconductor, housed in a miniature SOT-23-3 package. It utilizes advanced trench technology to deliver excellent RDS(ON), low gate charge, and efficient operation with gate voltages as low as 2.5V. This makes it perfectly suited for direct drive from 3.3V or 5V logic microcontrollers (like Arduino, ESP32) without requiring a gate driver IC. Key features include a drain-source voltage rating of 30V and a continuous drain current of up to 5.8A at 25°C. It is widely used in DC-DC converters, load switches, motor control, and power management in portable devices. Its small footprint saves PCB space, while its robust performance ensures reliability in various electronic designs. Choose the AO3400 for efficient, logic-level compatible switching in your next project.
