Silicon Diffused Power Transistor
BU4540AL
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.
