N-CHANNEL
ENHANCEMENT MODE

DESCRIPTION
The UTC UT2306 is N-channel power MOSFET, designed
with high density cell, with fast switching speed, ultra low
on-resistance and excellent thermal and electrical capabilities.
Used in commercial and industrial surface mount
applications and suited for low voltage applications such as
DC/DC converters.
