DESCRIPTION The BUL742A is manufactured using high voltage Multi Epitaxial Planar technology for high switching speeds and high voltage capability.
Thanks to an increased intermediate layer, it has an intrinsic ruggedness which enables the
transistor to withstand an high collector current level during brea...
