Description

AO3400 SMD Low Voltage N-Channel MOSFET SOT-23 Package

The AO3400 is a high-performance N-channel MOSFET designed for low-voltage, high-current switching applications. It operates efficiently with a low gate threshold voltage (typically around 1.0V) and offers low on-resistance (as low as 30mΩ at VGS = 4.5V), making it suitable for fast switching and reduced power loss. This makes it ideal for use in DC-DC converters, load switches, battery-powered circuits, and power management systems where efficiency and speed are critical.

Housed in a compact SOT-23 surface-mount package, the AO3400 is well-suited for space-constrained PCBs in modern electronic devices. Its maximum drain current rating of around 5.8A (at VGS = 4.5V) and drain-source voltage rating of 30V allow it to handle moderate power loads while maintaining thermal stability. The small footprint and surface-mount design also enable easy integration into automated manufacturing processes, making it a popular choice in consumer electronics, embedded systems, and other compact circuit designs.
