DESCRIPTION
The device is manufactured using high voltage
TO-220
Multi Epitaxial Planar technology for high
switchingspeeds and medium voltage capability.
It uses a Cellular Emitter structure with planar
edge termination to enhance switching speeds
while maintainingthe wide RBSOA.
The device is designed for use in lighting
