DESCRIPTION
The device is manufactured using high voltage
Multi Epitaxial Planar technology for high
switching speeds and high voltage capability.
It uses a Cellular Emitter structure with planar       INTERNAL SCHEMATIC DIAGRAM
edge termination to enhance switching speeds
while maintaining the wide RBSOA.
The device is designed for use in lighting
applications and low cost switch-mode power
supplies.
