ST83003 Description

Short technical summary and product information.

The STMicroelectronics ST83003 is a high voltage, fast-switching NPN power transistor manufactured using multi-epitaxial planar technology. It offers high switching speeds and high voltage capability, making it suitable for applications like electronic ballasts for fluorescent lighting. The device is designed to be coupled with its complementary PNP transistor, the ST93003.

 

Key electrical ratings include a collector-emitter voltage (VCEO) of 400V and a continuous collector current (IC) of 1.5A. The transistor has a maximum total power dissipation of 40W at 25°C. It is housed in a SOT-32-3 package, suitable for through-hole mounting.

 

This transistor utilizes a cellular emitter structure with planar edge termination to enhance switching speeds while maintaining a wide RBSOA. Its high voltage capability and fast switching characteristics are beneficial in power supply and lighting control circuits.
