Philips BU4525DL Datasheet
Philips Semiconductors Product specification
Silicon Diffused Power Transistor BU4525DL
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic envelope
with integrated damper diode intended 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.
