DESCRIPTION
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 device is designed for use in lighting
applications and low cost switch-mode power
supplies.
