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 STL series is designed for use in Compact

Fluorescent Lamps.
