Dual N-Channel Enhancement Mode MOSFET
General Description
These N-Channel Enhancement Mode MOSFETs are
produced using Fairchild Semiconductor's advance
process that has been especially tailored to minimize
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.

Notes:
1.
R
θJA
is the sum of the junction-to-case and case-to-ambient resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. R
θJC
is guaranteed by design while R
θCA
is determined by the user's board design.
a) 78° C/W when
mounted on a 0.5 in
2
pad of 2 oz. copper.
b) 125° C/W when
mounted on a 0.02 in
2
pad of 2 oz. copper.
c) 135° C/W when
mounted on a minimum
pad of 2 oz. copper.
