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 STN83003 is expressly designed for a new

solution to be used in compact fluorescent lamps,

where it is coupled with the STN93003, its

complementary PNP transistor.
