AO3420
AO3420 is N-Channel MOSFET manufactured by Alpha & Omega Semiconductors.
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.
