BU4508AF

DISCRETE SEMICONDUCTORS DATA SHEET BU4508AF Silicon Diffused Power Transistor Product specification Supersedes data of January 1998 File under Discrete Semiconductors, SC06 June 1998 Philips Semiconductors Product specification Silicon Diffused Power Transistor BU4508AF 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 an p.c monitors. Features exceptional tolerance to base drive and collector current load variations resulting in a very low worst case dissipation.
