AO4421
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4421 uses advanced trench technology to
provide excellent RDS(ON), and ultra-low low gate
charge. This device is suitable for use as a load
switch or in PWM applications. Standard Product
AO4412 is Pb-free (meets ROHS & Sony 259
specifications). AO4421L is a Green Product
ordering option. AO4421 and AO4421L are
electrically identical.
Features
VDS (V) = -60V
ID = -6.2 A (VGS = -10V)
RDS(ON) < 40mΩ (VGS = -10V)
RDS(ON) < 50mΩ (VGS = -4.5V)
