NPN Bipolar Power Transistor
For Switching Power Supply Applications
The BUL146/BUL146F have an applications specific state–of–the–art die designed
for use in fluorescent electric lamp ballasts to 130 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)
• Full Characterization at 125°C
• Parametric Distributions are Tight and Consistent Lot–to–Lot
• Two Package Choices: Standard TO–220 or Isolated TO–220
• BUL146F, Isolated Case 221D, is UL Recognized to 3500 V
