Description
The BUL1203E is manufactured using diffused collector in planar technology to enhance switching speeds and tight hFE range while maintaining a wide RBSOA.
Thanks to his enhanced high voltage structure 1 (EHVS1) 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.

FEATUREs
• High voltage capability
• Low spread of dynamic parameters
• Minimum lot-to-lot spread for reliable operation
• Very high switching speed

APPLICATIONs
• Electronic ballast for fluorescent lighting
• Switch mode power supplies
