® BUL1203E HIGH VOLTAGE FAST-SWITCHING NPN POWER TRANSISTOR s s s s HIGH VOLTAGE CAPABILITY LOW SPREAD OF DYNAMIC PARAMETERS MINIMUM LOT-TO-LOT SPREAD FOR RELIABLE OPERATION VERY HIGH SWITCHING SPEED s APPLICATIONS ELECTRONIC BALLASTS FOR FLUORESCENT LIGHTING (277 V HALF BRIDGE AND 120 V PUSH-PULL TOPOLOGIES) TO-220 3 1 2 DESCRIPTION The BUL1203E is a new device manufactured using Diffused Collector technology to enhance switching speeds and tight h FE 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.
