Product Summary

General Description
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. Standard Product AO3420 is Pb-free 
(meets ROHS & Sony 259 specifications). AO3420L 
is a Green Product ordering option. AO3420 and 
AO3420L are electrically identical.
