Description
The device is manufactured using high voltage
multi-epitaxial planar technology for high
switching speeds and high voltage capability.
Figure 1.
Internal schematic diagram
It uses a cellular emitter structure with planar
edge termination to enhance switching speeds
while maintaining the wide RBSOA.
The STL series is designed for use in compact
fluorescent lamps.
