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:
ÐHigh and Flat DC Current Gain h FE
ÐFast Switching
ÐNo 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

Figure 17. Forward Bias Power Derating
There are two limitations on the power handling ability of a transistor: average junction temperature and second breakdown. Safe operating area curves indicate IC ± VCE limits of the transistor that must be observed for reliable operation; i.e., the transistor must not be subjected to greater dissipation than the curves indicate. The data of Figure 15 is based on TC = 25°C; TJ(pk) is variable depending on power level. Second breakdown pulse limits are valid for duty cycles to 10% but must be derated when TC > 25°C. Second breakdown limitations do not derate the same as thermal limitations. Allowable current at the voltages shown in Figure 15 may be found at any case temperature by using the appropriate curve
on Figure 17. TJ(pk) may be calculated from the data in Figure 20 and 21. At any case temperatures, thermal limitations will
reduce the power that can be handled to values less than the limitations imposed by second breakdown. For inductive loads, high voltage and current must be sustained simultaneously during turn±off with the base±to±emitter junction reverse±biased. The safe level is specified as a reverse± biased safe operating area (Figure 16). This rating is verified under clamped conditions so that the device is never subjected to an avalanche mode.
