Dual N-Channel Enhancement Mode Field Effect Transistor
General Description
SO-8 N-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 provide superior switching
performance and minimize on-state resistance. These
devices are particularly suited for low voltage applications
such as disk drive motor control, battery powered circuits
where fast switching, low in-line power loss, and resistance
to transients are needed.
Features
3.5 A, 60 V. R_DS(ON) = 0.100 Ω @ V_GS = 10 V,
R_DS(ON) = 0.200 Ω @ V_GS = 4.5 V.
High density cell design for extremely low R_DS(ON).
High power and current handling capability in a widely
used surface mount package.
Dual MOSFET in surface mount package.
