AO3422 Description

Short technical summary and product information.

The AO3422 is an N-Channel enhancement mode field effect transistor manufactured by Alpha & Omega Semiconductor using advanced trench technology. It is designed for low voltage switching applications and offers a maximum drain-source voltage of 55V and a continuous drain current of 2.1A at 25°C ambient temperature.

 

The device features a low on-resistance of 160mΩ maximum at Vgs=4.5V and 200mΩ maximum at Vgs=2.5V, enabling efficient operation across a wide gate drive range from 2.5V to 12V. The AO3422 also provides fast switching performance with typical turn-on delay of 2.3ns and turn-off delay of 16.5ns.

 

This MOSFET is suitable for use as a load switch and other general purpose switching applications. It is packaged in a compact SOT23-3 surface-mount package and supports an operating junction temperature range of -55°C to 150°C.
