Description
The device is manufactured using high voltage
Figure 1. Internal schematic diagram
multi epitaxial planar technology for high switching
speeds and high voltage capability. It uses a
cellular emitter structure with planar edge
termination to enhance switching speeds while
maintaining the wide RBSOA. The ST83003 is
expressly designed for a new solution to be used
in compact fluorescent lamps, where it is coupled
with the ST93003, its complementary PNP
transistor.
