AO3423
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO3423 uses advanced trench technology to
provide excellent R
DS(ON)
, low gate charge and
operation with gate voltages as low as 2.5V. This
device is suitable for use as a load switch or in PWM
applications. It is ESD protected.
Standard Product
AO3423 is Pb-free (meets ROHS & Sony 259
specifications). AO3423L is a Green Product
ordering option. AO3423 and AO3423L are
electrically identical.
