BUD43B
BUD43B is NPN Silicon Planar Power Transistor manufactured by onsemi.
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 h FE
- Fast and Tightened Switching Distributions
- No Coil Required in Base Circuit for Fast Turn- off
(no current tail)
