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