Product specification

Silicon Diffused Power Transistor

BU1508DX

GENERAL DESCRIPTION

Enhanced performance, new generation, high-voltage, high-speed switching npn transistor with an integrated

damper diode 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.
