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 anti-
parallel 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.
The integrated diode has minimal charge
coupling with the transistor, increasing frequency
stability, especially in lower power circuits where
the circulating currents are low. By design, this
new device offers a voltage matched integrated
transistor and anti-parallel diode.
