DESCRIPTION

The BUL1203E is a new device manufactured

using Diffused Collector technology to enhance

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.
