BU2508DW

Philips Semiconductors Product specification Silicon Diffused Power Transistor BU2508DW GENERAL DESCRIPTION Enhanced performance, new generation, high-voltage, high-speed switching npn transistor with an integrated damper diode in a plastic envelope intended for use in horizontal deflection circuits of colour television receivers. Features exceptional tolerance to base drive and collector current load variations resulting in a very low worst case dissipation.
