The Alpha & Omega Semiconductor Inc. AO4478 is an N-Channel enhancement mode power MOSFET designed for demanding applications. This component features a Drain-Source Voltage (Vdss) of 30V and a continuous drain current rating (Id) of 9A at 25°C, with a maximum power dissipation of 3.1W (Ta). Its low on-resistance of 19mOhm at 9A and 10V gate drive makes it suitable for efficient power switching. The AO4478 utilizes advanced MOSFET technology and is supplied in a compact 8-SOIC package for surface mounting, commonly found in automotive, industrial control, and power management systems. Key electrical characteristics include a gate charge (Qg) of 11 nC (max) at 10V and input capacitance (Ciss) of 560 pF (max) at 15V. It operates across a wide temperature range of -55°C to 150°C (TJ) and supports a gate-source voltage (Vgs) up to ±25V.
