BUD43B
SWITCHMODEt
NPN Silicon Planar Power
Transistor
The BUD43B has an application specific state−of−the−art die designed for use in 220 V line operated Switchmode Power supplies and electronic ballast (“light ballast”).
The main advantages brought by this new
transistor are:
• Improved Efficiency Due to Low Base Drive Requirements: • High and Flat DC Current Gain hFE • Fast and Tightened Switching Distributions • No Coil Required in Base Circuit for Fast Turn−off
