NPN Bipolar Power Transistor
For Switching Power Supply Applications
*Motorola Preferred Device
The BUL44/BUL44F 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)
• Full Characterization at 125°C
• Tight Parametric Distributions are Consistent Lot–to–Lot
• Two Package Choices: Standard TO–220 or Isolated TO–220
• BUL44F, 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 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 on 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 than 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.
