Philips BU4523DF Datasheet
Philips Semiconductors Objective specification
Silicon Diffused Power Transistor BU4523DF
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor in a plastic envelope
with an 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.
