 Silicon Diffused Power Transistor
BU2508AW 
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic envelope
intended for use in horizontal deflection circuits of colour television receivers. Features exceptional tolerance to
base drive and collector current load variations resulting in a very low worst case dissipation.
