description
The new BULDxx range of transistors have been designed specifically for use in High Frequency Electronic Ballasts (HFEB’s). This range of switching transistors has tightly controlled storage times and an integrated fast trr antiparallel diode. The revolutionary design ensures that the diode has both fast forward and reverse recovery times, achieving the same performance as a discrete anti-parallel diode plus transistor.
