AOD438
N-Channel Enhancement Mode Field Effect Transistor
General Description
Features
The AOD438 uses advanced trench technology to
provide excellent RDS(ON), low gate charge and low
gate resistance. This device is ideally suited for use
as a low side switch in CPU core power conversion.
Standard Product AOD438 is Pb-free (meets ROHS
& Sony 259 specifications). AOD438L is a Green
Product ordering option. AOD438 and AOD438L are
electrically identical.
VDS (V) = 30V
ID = 85A (VGS = 10V)
RDS(ON) < 3.5mΩ (VGS = 10V)
RDS(ON) < 5.5mΩ (VGS = 4.5V)
