TrenchMOS™ transistor
Logic level FET
GENERAL DESCRIPTION
N-channel enhancement mode logic
level field-effect power transistor in a
plastic envelope using ’trench’
technology. The device features very
low on-state resistance and has
integral zener diodes giving ESD
protection up to 2kV. It is intended for
use in automotive and general
purpose switching applications.
