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