DESCRIPTION
The BU406D and BU407D are silicon planar
epitaxial NPN transistors with integrated damper
diode, in Jedec TO-220 plastic package. They
are fast switching, devices for use in horizontal
deflection output stages of MTV receivers with INTERNAL SCHEMATIC DIAGRAM
110o CRT.
The BU406D is primarily intended for large
screen, while the BU407D is for medium and
small screens
