Overview
The STN83003 is a high voltage fast-switching NPN power transistor manufactured by STMicroelectronics. It is specifically designed for applications in compact fluorescent lamps, where it is often paired with its complementary PNP transistor, the STN93003. This transistor utilizes high voltage multi-epitaxial planar technology to achieve high switching speeds and medium voltage capability. The cellular emitter structure with planar edge termination enhances switching speeds while maintaining a wide Reverse Bias Safe Operating Area (RBSOA).
