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 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

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 T
C
= 25°C; T
J(pk)
is variable depending on power level. Second
breakdown pulse limits are valid for duty cycles to 10% but
must b e derated when TC > 25°C. S econd b reakdown
limitations do not derate the same as thermal l imitations.
Allowable current at the voltages shown in Figure 15 may be
found at any case temperature by using the appropriate curve
on Figure 17. T
J(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 c lamped c onditions s o that t he device i s never
subjected to an avalanche mode.

Laboratory tests on a limited number of samples indicate, when using the screw and compression washer mounting technique, a screw
torque of 6 to 8 in.lbs is sufficient to provide maximum power dissipation capability. The compression washer helps to maintain a
constant pressure on the package over time and during large temperature excursions.
Destructive laboratory tests show that using a hex head 4–40 screw, without washers, and applying a torque in excess of 20 in.lbs will
cause the plastic to crack around the mounting hole, resulting in a loss of isolation capability.
Additional tests on slotted 4–40 screws indicate that the screw slot fails between 15 to 20 in.lbs without adversely affecting the package. However, in order to positively ensure the package integrity of the fully isolated device, Motorola does not recommend exceeding 10
in.lbs of mounting torque under any mounting conditions.
