AO3422
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO3422 uses advanced trench technology to
provide excellent R
DS(ON)
and low gate charge. It
offers operation over a wide gate drive range from
2.5V to 12V. This device is suitable for use as a load
switch. Standard product
AO3422 is Pb-free (meets
ROHS & Sony 259 specifications). AO3422L is a
Green Product ordering option. AO3422 and
AO3422L are electrically identical.
