AO3400 MOSFET 30V 5.8A SOT-23-3L Package

The AO3400 MOSFET is a compact, high-efficiency N-Channel Enhancement Mode MOSFET designed for low-voltage, high-speed switching applications. With a drain-source voltage of 30V and a continuous drain current of 5.8A, it is ideal for space-constrained applications like DC-DC converters, battery-powered circuits, logic-level load switching, and microcontroller-based designs.

Its low Rds(on) of 34mΩ at Vgs = 4.5V ensures minimal power loss and heat generation, while the low gate threshold voltage of 0.7V makes it fully compatible with 3.3V and 5V logic levels such as Arduino, STM32, ESP32, and Raspberry Pi.
