40V N-Channel PowerTrench
MOSFET
General Description
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
“low side” synchronous rectifier operation, providing an
extremely low R
DS(ON)
in a small package.
Applications
Synchronous rectifier
DC/DC converter

Notes:
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.
