® BUL742A
HIGH VOLTAGE FAST-SWITCHING
NPN POWER TRANSISTOR
s HIGH VOLTAGE CAPABILITY
s LOW SPREAD OF DYNAMIC PARAMETERS
s MINIMUM LOT-TO-LOT SPREAD FOR
RELIABLE OPERATION
s VERY HIGH SWITCHING SPEED
APPLICATIONS
s FOUR LAMP ELECTRONIC BALLAST FOR:
120 V MAINS IN PUSH-PULL
CONFIGURATION;
277 V MAINS IN HALF BRIDGE CURRENT
FEED CONFIGURATION.
s SWITCH MODE POWER SUPPLIES
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 breakdown condition, without using
the transil protection usually necessary in typical
converters for lamp ballast.
