DESCRIPTION                                                    ISOWATT218
The BUH515 is manufactured using Multiepitaxial
Mesa technology for cost-effective high
performance and uses a Hollow Emitter structure
to enhance switching speeds.
The BUH series is designed for use in horizontal
deflection circuits in televisions and monitors.       INTERNAL SCHEMATIC DIAGRAM
