SWITCHMODE™
NPN Bipolar Power Transistor For Switching Power Supply Applications

The MJE/MJF18008 have an applications specific state–of–the–art die designed for use in 220 V line–operated Switchmode Power supplies and electronic light ballasts. These high voltage/high speed transistors offer the following:

• 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)
• Tight Parametric Distributions are Consistent Lot–to–Lot
• Two Package Choices: Standard TO–220 or Isolated TO–220
• MJF18008, Case 221D, is UL Recognized at 3500 VRMS: File #E69369
