## **STN83003** High voltage fast-switching NPN power transistor 

## **Features** 

- High voltage capability 

- Very high switching speed 

## **Application** 

- Electronics ballasts for fluorescent lighting 

## **Description** 

The device is manufactured using high voltage multi-epitaxial planar technology for high switching speeds and high 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.
