MODE FIELD EFFECT
TRANSISTOR
DESCRIPTION
The UT3418 uses advanced trench technology to provide
excellent RDS(ON), low gate charge and operation with low gate
voltages. This device is suitable for use as a load switch or in
PWM applications.
FEATURES
* RDS(ON) < 60mΩ @VGS = 10 V
* RDS(ON) < 70mΩ @VGS = 4.5 V
* RDS(ON) < 155mΩ @VGS = 2.5 V
* Low capacitance
* Low gate charge
* Fast switching capability
* Avalanche energy specified
