Motorola Bipolar Power Transistor Device Data
The BUH100 has an application specific state–of–art die designed for use in
100 Watts Halogen electronic transformers.
This power transistor is specifically designed to sustain the large inrush current
during either the start–up conditions or under a short circuit across the load.
This High voltage/High speed product exhibits the following main features:
• Improved Efficiency Due to the Low Base Drive Requirements:
— High and Flat DC Current Gain h
FE
— Fast Switching
• Robustness Thanks to the Technology Developed to Manufacture
this Device
• Motorola “6 SIGMA” Philosophy Provides Tight and Reproducible

Motorola Bipolar Power Transistor Device Data
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 22 is based
on TC = 25°C; T
J(pk)
is variable depending on power level.
Second breakdown pulse limits are valid for duty cycles to
10% b ut m ust b e derated w hen TC > 2 5°C. S econd
breakdown limitations do not derate the same as thermal
limitations. Allowable current at t he voltages shown on
Figure 22 may be found at any case temperature by using
the appropriate curve on Figure 21.
T
J(pk)
may be calculated from the data in Figure 24. At any
case temperatures, thermal limitations will reduce the power
that can be h andled 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 23). T his rating is verified under clamped
conditions s o that t he device is n ever s ubjected t o an
avalanche mode.
