DESCRIPTION
The devices are manufactured using high voltage
Multi Epitaxial Planar technology for high
switching speeds and medium voltage capability.
They use a Cellular Emitter structure with planar
edge termination to enhance switching speeds.
The devices are designed for use in lighting
applications and low cost switch-mode power
supplies.
