MJE18008/D
MJE18008, MJF18008
Switch-mode 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 switch−mode Power
supplies and electronic light ballasts.
Features
• Improved Efficiency Due to Low Base Drive Requirements:
♦ High and Flat DC Current Gain h
FE
♦
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 V
RMS
: File
#E69369
• These Devices are Pb−Free and are RoHS Compliant*

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Pulse Test: Pulse Width = 5 ms, Duty Cycle ≤ 10%.
2. Proper strike and creepage distance must be provided.
