Silicon Diffused Power Transistor
BU4540AW
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 and p.c monitors. Features exceptional tolerance to base drive and collector current load variations resulting in a very low worst case dissipation.
