AO4440 Datasheet, PDF (1/4 Pages) Alpha & Omega Semiconductors – N-Channel Enhancement Mode Field Effect Transistor

AO4440
60V N-Channel MOSFET
General Description
The AO4440 uses advanced trench technology to provide excellent R_DS(ON)and low gate charge. This
device is suitable for use as a load switch or in PWM applications.
