The AO3403 is a P-channel MOSFET from Alpha & Omega Semiconductor. It features a drain-source voltage rating of -30V and a continuous drain current of -2.6A at 25°C ambient. The device uses advanced trench technology to achieve low on-resistance and low gate charge, making it suitable for load switching and PWM applications.
The device offers a maximum on-resistance of 115 mΩ at Vgs=-10V and 150 mΩ at Vgs=-4.5V, with typical values of 88 mΩ and 103 mΩ respectively. It operates over a junction temperature range of -55°C to 150°C and has a maximum power dissipation of 1.4W at 25°C ambient.
The AO3403 is available in a SOT-23-3 surface mount package, suitable for compact PCB designs. It is designed for applications such as power management, battery protection, and DC-DC converters.
