Technical information

The STX83003 is together with the PNP-Type STX93003 developed for Compact Fluorescent Lamps (CFL) , As this complementary pair coupled with the resonant driving method represents an application breakthrough in the CFL design. It is based on a half bridge voltage fed topology and works using an auxiliary winding on the inductor in series with the lamp, in order to generate the waveform of the resonant driving circuit (see example below).
The device is manufactured using high voltage Multi Epitaxial Planar technology for high switching speeds and medium voltage capability. It uses a Cellular Emitter structure with planar edge termination to enhance switching speeds while maintaining the wide RBSOA. The STX83003 is expressly designed for a solution to be used in compact fluorescent lamps, where it is coupled with the STX93003, its complementary PNP transistor.
