SWITCHMODE 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
— (no current tail)
