Philips BU4522DX Datasheet
Philips Semiconductors Objective specification
Silicon Diffused Power Transistor BU4522DX
GENERAL DESCRIPTION
Enhanced performance, new generation, high-voltage, high-speed switching npn transistor with an integrated
damper diode in a plastic full-pack envelope 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.
