Fast switching speed.
Low gate charge (typical 5 nC).
High performance trench technology for extremely low
R
DS(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.
