AO7400 Description

Short technical summary and product information.

The AO7400 is an N-Channel MOSFET from Alpha & Omega Semiconductor built with advanced trench technology. It features a maximum drain-source voltage of 30V and continuous drain current of 1.7A at 25°C ambient temperature. The device offers low on-resistance with typical values of 45mΩ at 10V gate drive, 50mΩ at 4.5V, and 61mΩ at 2.5V, enabling efficient operation at low gate voltages.

Gate threshold voltage ranges from 0.5V minimum to 1.4V maximum, and the gate can be driven up to ±12V. Input capacitance is typically 185pF at 15V, and total gate charge is 10nC typical at 10V. The MOSFET is capable of handling pulsed drain currents up to 15A and has a maximum power dissipation of 350mW at 25°C.

The AO7400 is supplied in a surface mount SC-70-3 (SOT-323) package, making it suitable for compact designs. It operates over a wide junction temperature range of -55°C to 150°C. Typical applications include load switching, low current inverters, and low current DC-DC converters.
