AO3702
N-Channel Enhancement Mode Field Effect Transistor
with Schottky Diode
General Description
The AO3702/L uses advanced trench technology to provide
excellent R
DS(ON)
, low gate charge.
A Schottky diode is provided to facilitate the implementation of
a bidirectional blocking switch, or for DC-DC conversion
applications. AO3702 and AO3702L are electrically identical.
-RoHs Complaint
-AO3702L is Halogen Free
