transistor
GENERAL DESCRIPTION
N-channel enhancement mode
standard 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 switched mode
power supplies and general purpose
switching applications.
