The AO3400 MOSFET is a small signal, RoHS-compliant MOSFET manufactured by Microdiode Electronics. It is a SOT-23 form factor device, allowing for a small package size for board mounting. It is specifically designed to handle high frequencies and has a very low drain-to-source on-resistance of 1.4O. It has a maximum drain current of 1.5A, a gate-source voltage of 14V, and a maximum power dissipation of 250mW. It is also highly efficient and has a fast switching frequency. It is suitable for applications such as DC to DC conversion, signal processing, power management, and, to a lesser degree, motor control.
