NDS8434A
Single P-Channel Enhancement Mode Field Effect Transistor
General Description
SO-8 P-Channel enhancement mode power field effect
transistors are produced using Fairchild's proprietary, high cell
density, DMOS technology. This very high density process is
especially tailored to minimize on-state resistance and provide
superior switching performance. These devices are particularly
suited for low voltage applications such as notebook computer
power management and other battery powered circuits where
fast switching, low in-line power loss, and resistance to
transients are needed.
Features
-7.8 A, -20 V. R_DS(ON) = 0.024 Ω @ V_GS = -4.5 V
R_DS(ON) = 0.032 Ω @ V_GS = -2.5V.
High density cell design for extremely low R_DS(ON).
High power and current handling capability in a widely used
surface mount package.
