DESCRIPTION
The BUH315 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 INTERNAL SCHEMATIC DIAGRAM
deflection circuits in televisions and monitors.
