AO3420
20V N-Channel MOSFET
General Description
The AO3420 uses advanced trench technology to provide excellent R
DS(ON)
, low gate charge and operation with gate
voltages as low as 1.8V while retaining a 12V V
GS(MAX)
rating. This device is suitable for use as a uni-directional
or bi-directional load switch.
