AO4438
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4438 uses advanced trench technology to
provide excellent R_DS(ON) and low gate charge. This
device is suitable for use as a load switch or in PWM
applications. Standard Product AO4438 is Pb-free
(meets ROHS & Sony 259 specifications). AO4438L
is a Green Product ordering option. AO4438 and
AO4438L are electrically identical.
