Product Specification
BUK444-200A/B
GENERAL DESCRIPTION
N-channel enhancement mode
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 general purpose switching
applications.
