2N3791 Description

Short technical summary and product information.

The 2N3791 is a silicon epitaxial-base PNP power transistor manufactured by STMicroelectronics, housed in a TO-3 metal case. This component is engineered for robust performance in power linear and switching applications.

 

Key electrical characteristics include a maximum collector current of 10A and a maximum base current of 4A. It can handle a total device dissipation of 150 Watts at a case temperature of 25°C. The junction temperature can reach up to 200°C, with storage temperatures ranging from -65°C to +200°C.

 

Thermal management is supported by a low thermal resistance from junction to case of 1.17°C/W. The transistor offers a collector-emitter sustaining voltage of up to 60V (VCEO(SUS)) under specific conditions and an emitter-base voltage rating of 7V.

 

Designed for through-hole mounting, the 2N3791 is suitable for applications requiring reliable power handling capabilities. Its complementary NPN type is the 2N3713 series.
