The BUL147/BUL147F have an applications specific state–of–the–art die designed
for use in electric fluorescent lamp ballasts to 180 Watts and in Switchmode Power
supplies for all types of electronic equipment. These high–voltage/high–speed
transistors offer the following:
•
Improved Efficiency Due to Low Base Drive Requirements:
— High and Flat DC Current Gain
— Fast Switching
— No Coil Required in Base Circuit for Turn–Off (No Current Tail)
Parametric Distributions are Tight and Consistent Lot–to–Lot
Two Package Choices: Standard TO–220 or Isolated TO–220
