PowerMOS transistor
Logic level FET
GENERAL DESCRIPTION
N-channel enhancement mode
logic level field-effect power
transistor in a plastic full-pack
envelope.
The device is intended for use in
Switched Mode Power Supplies
(SMPS), motor control, welding,
DC/DC and AC/DC converters, and
in automotive and general purpose
switching applications.
