AO4402

Overview

The AO4402 is an N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to deliver low on-resistance and minimal gate charge, supporting operation with gate voltages as low as 2.5V. Key electrical parameters include a drain-source voltage (Vds) of 30V and a continuous drain current (Id) of 12A. The device exhibits an on-resistance (Rds(on)) of less than 14mΩ at Vgs=10V, less than 16mΩ at Vgs=4.5V, and less than 22mΩ at Vgs=2.5V.
