• Manufacturer Part Number: bu4508af-hg
• Description: Bu4508af Silicon Diffused Power Transistor
• Manufacturer: NXP Semiconductors

Philips Semiconductors
June 1998
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.
