Philips BU4525DF Datasheet
Philips Semiconductors Objective specification
Silicon Diffused Power Transistor BU4525DF
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic full-pack
envelope with integrated damper diode intended for use in horizontal deflection circuits of colour television receivers
and p.c monitors. Features exceptional tolerance to base drive and collector current load variations resulting in a
very low worst case dissipation.
