AO3423

Overview

The AO3423 is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to deliver low on-resistance and gate charge, supporting operation with gate voltages as low as 2.5V. The device features a drain-source voltage of -20V and a continuous drain current of -2A at VGS=-10V. At this gate voltage, the maximum on-resistance is less than 92mΩ. Additional resistance limits are specified as less than 118mΩ at VGS=-4.5V and less than 166mΩ at VGS=-2.5V. It is housed in an SOT-23 package.
