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.

This device is available in the now well established 8 pin low height surface mount D package, and the TO­220 pin compatible SL package. Use of the SL package allows for a 40% height saving, making it ideal for
compact ballast applications.
