The BUH51 has an application specific state±of±art die designed for use in 50 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:

ÐHigh and Flat DC Current Gain h FE

ÐFast Switching

Robustness Thanks to the Technology Developed to Manufacture this Device

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; 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 22 may be found at any case temperature by using the appropriate curve on Figure 21.

TJ(pk) may be calculated from the data in Figure 24. 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 23). This rating is verified under clamped conditions so that the device is never subjected to an avalanche mode.
