AO4478_10 Datasheet, PDF (1/6 Pages) Alpha & Omega Semiconductors – 30V N-Channel MOSFET

AO4478
30V N-Channel MOSFET
General Description
The AO4478 uses advanced trench technology to
provide excellent R_DS(ON), low gate charge. This
device is suitable for use as general puspose, PWM and
a load switch applications.
