AO4403 P-Channel Enhancement Mode Field Effect
Transistor
General Description
The AO4403 uses advanced trench technology to provide excellent RDS(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. The source leads are separated to allow a Kelvin connection to the source, which may be used to bypass the source inductance.
Features
VDS (V) = -30V ID = -6.1 A RDS(ON) < 46mΩ (VGS = -10V) RDS(ON) < 61mΩ (VGS = -4.5V) RDS(ON) < 117mΩ (VGS = -2.5V)
