General Description  
N-Channel PowerTrench

®

MOSFET  
This  
N-Channel  
MOSFET  
is produced using
ON  
Semiconductor’s advanced PowerTrench

®

process that has  
been especially tailored to minimize the on-state resistance. This  
device is well suited for Power Management and load switching  
applications common in Notebook Computers and Portable  
Battery Packs.
