BUL1203E high voltage fast-switching npn power transistor n high voltage capability n low spread of dynamic parameters n minimum lot-to-lot spread for reliable operation n very high switching speed applications n electronic ballasts for fluorescent lighting (277 v half bridge and 120 v push-pull topologies) 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 curr ent level during breakdown condition, without using the transil protection usually necessary in typical converters for lamp ballast. ? internal schematic diagram june 2001 absolute maximum ratings symbol parameter value unit v ces collector-emitter voltage (v be = 0) 1200 v v ceo collector-emitter voltage (i b = 0) 550 v v ebo emitter-base voltage (i c = 0) 9 v i c collector current 5 a i cm collector peak current (t p < 5 ms) 8 a i b base current 2 a i bm base peak current (t p < 5 ms) 4 a p tot total dissipation at t c = 25 o c 100 w t stg storage temperature -65 to 150 o c t j max. operating junction temperature 150 o c 1 2 3 to-220 1/4
