Dual N-Channel Logic Level PWM Optimized PowerTrench
MOSFET
General Description
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.

1. R
θJA
is the sum of the junction-to-case and case-to-ambient thermal 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.
