NPN Bipolar Power Transistor
For Switching Power Supply Applications
*Motorola Preferred Device
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 types of electronic equipment. These high 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 VRMS: File #E69369

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 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.

Figure 23. Typical Mounting Techniques
for Isolated Package
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.
