DESCRIPTION
The BUL1203E is a new device manufactured using Diffused Collector technology to enhance switching speeds and tight hFE range while maintaining a wide RBSOA.
Thanks to his structure it has an intrinsic ruggedness which enables the transistor to withstand a high collector current level during Breakdown condition, without using the transil protection usually necessary in typical converters for lamp ballast.

■ HIGH VOLTAGE CAPABILITY
■ LOW SPREAD OF DYNAMIC PARAMETERS
■ MINIMUM LOT-TO-LOT SPREAD FOR RELIABLE OPERATION
■ VERY HIGH SWITCHING SPEED

APPLICATIONS
■ ELECTRONIC BALLASTS FOR FLUORESCENT LIGHTING (277 V HALF BRIDGE AND 120 V PUSH-PULL TOPOLOGIES)
