DESCRIPTION
The     BUH515D         is    manufactured using                ISOWATT218
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.
