DESCRIPTION
The BU407FI is a silicon epitaxial planar NPN                                              3
transistors in ISOWATT220 plastic package.                                             2
                                                                                   1
It is a fast switching, high voltage device for use
in horizontal deflection output stages of medium
and small screens MTV receivers with 110o CRT                         ISOWATT220
as monochrome computer terminals.
