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.
