DESCRIPTION
The BUX48/A, BUV48A and BUV48AFI are
silicon Multiepitaxial Mesa NPN transistors
mounted respectively in TO-3 metal case, TO-218
plastic package and ISOWATT218 fully isolated
package. They are particulary intended for
switching and industrial applications from single
and tree-phase mains.
