Silicon Diffused Power Transistor
BU4507DF
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic full-pack
envelope with an integrated damper diode intended for use in horizontal deflection circuits of colour television
receivers and computer monitors. Features exceptional tolerance to base drive and collector current load variations
resulting in a very low worst case dissipation.
