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.
