The MJE/MJF18009 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”). These high voltage/high speed transistors exhibit the following main features:

• Improved Efficiency Due to Low Base Drive Requirements: High and Flat DC Current Gain hFE Fast Switching No Coil Required in Base Circuit for Turn–Off (No Current Tail)

• Full Characterization at 125
C

• ON Semiconductor “6 SIGMA” Philosophy Provides Tight and Reproducible Parametric Distributions

• Specified Dynamic Saturation Data

• Two Package Choices: Standard TO–220 or Isolated TO–220
