Technical information

The ST93003 is together with the NPN-Type ST83003 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 above).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 ST93003 is expressly designed for a new solution to be used in compact fluorescent lamps, where it is coupled with the ST83003, its complementary NPN transistor.
