Product specification
BU2508AX
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic full-pack
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.
