SWITCHMODE
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 t ypes of electronic equipment. These h igh 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
