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

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

• Specified Dynamic Saturation Data

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