General Description
The AOD408 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 AOD408 is Pb-
free (meets ROHS & Sony 259 specifications).
AOD408L is a Green Product ordering option.
AOD408 and AOD408L are electrically identical.
