Philips BU4515AX Datasheet
Philips Semiconductors Product specification
Silicon Diffused Power Transistor BU4515AX
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.
