FDS8949
Dual N-Channel Logic Level PowerTrench® MOSFET
40V, 6A, 29mΩ
Features
General Description
Max rDS(on) = 29mΩ at VGS = 10V
Max rDS(on) = 36mΩ at VGS = 4.5V
Low gate charge
High performance trench technology for extremely low
rDS(on)
High power and current handling capability
These N-Channel Logic Level MOSFETs are produced
using Fairchild
Semiconductor’s advanced
PowerTrench® process that has been especially tailored
to minimize the on-state resistance and yet maintain
superior switching performance.
These devices are well suited for low voltage and
battery powered applications where low in-line power
loss and fast switching are required.
RoHS compliant
