BU4540

Philips Semiconductors Objective specification 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.
