AO3401

Overview

The AO3401 is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It utilizes advanced trench technology to achieve low on-resistance and gate charge, supporting operation with gate voltages as low as 2.5V. The device features a drain-source voltage of -30V and a continuous drain current of -4.0A at VGS=-10V. Key electrical parameters include an on-resistance of less than 50mΩ at VGS=-10V, a maximum gate-source voltage of ±12V, and a power dissipation of 1.4W at 25°C. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

Advanced trench technology for excellent RDS(ON) and low gate charge
Compatible with logic level gate voltages down to 2.5V
Suitable for load switch and PWM applications

Applications

Load switching circuits
Pulse Width Modulation (PWM) applications
