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.
