Texas Instruments GOJAN 2N3791 Vintage TO-3 PNP Silicon Power Transistor
$24.99
Original Texas Instruments GOJAN 2N3791 PNP silicon power transistor housed in the classic TO-3 metal can package. This USA-made device has been professionally tested and verified functional with strong gain, excellent saturation characteristics, and no measurable collector leakage. Suitable for vintage electronics restoration, industrial controls, communications equipment, power supplies, audio amplifiers, and semiconductor collections. The rugged TO-3 package was designed for demanding power applications requiring efficient heat dissipation and long-term reliability.
Historical Note:
Texas Instruments was one of the pioneers of the semiconductor industry and produced a wide range of power transistors throughout the 1960s, 1970s, and 1980s. The 2N3791 was commonly used in industrial electronics, communications equipment, power supplies, and amplifier applications. USA-manufactured TI power semiconductors from this era remain highly desirable for restoration projects and vintage electronics collections.
