DISCRETE AND STANDARD ICs GROUP BUL39D/BUL49D/BUL59 BUL39D/BUL49D/BUL59 by F. Romano Transistor Product Marketing NEW BIPOLAR TRANSISTORS FOR ELECTRONIC TRANSFORMERS R BUL39D BUL39D T'1 C2 T1 D C1 C3 BUL39D BUL39D T"1 Typical electronic tranformer circuit Following the increasing demand for devices dedicated to lighting applications, ST has introduced three new bipolar transistors designed specifically for electronic transformers: BUL39D BUL39D - BUL49D BUL49D - BUL59 BUL59. FEATURES The main requirement of a transistor operating in lighting applications is the ability to withstand the high current flowing through the device during start up and short circuits. The increased ruggedness of these new devices improves the safety margins when the transistor operates in such conditions. The new devices are also able to guarantee Device BULK128D BULK128D BULK38D BULK38D BUL39D BUL39D BUL38D BUL38D BUL49D BUL49D BUL58D BUL58D BUL59 BUL59 BUL67 BUL67 BUL510 BUL510 BUL87 BUL87 BUL810 BUL810 a Reverse Biased Safe Operating Area with a Vcew capability up to 450V at high current level. BUL39D BUL39D AND BUL49D BUL49D The collector-emitter saturation voltage has been reduced in the three new devices, and the diode forward voltage in the two devices with the built-in free-wheeling diode. This helps to minimize the transistors losses in the application, while the controlled switching time spread guarantees a stable and symmetrical operation of a pair of power switches present in the typical electronic transformer circuit.
