RCA 2N4347 Vintage TO-3 NPN Silicon Power Transistor
$24.99
Original RCA 2N4347 NPN silicon power transistor housed in the classic TO-3 metal can package. This vintage RCA device has been professionally tested and verified functional with good gain, excellent saturation characteristics, and no measurable collector leakage. Suitable for vintage electronics restoration, industrial equipment repair, communications equipment, power supplies, amplifier circuits, power control systems, and semiconductor collections. The rugged TO-3 package provides excellent heat dissipation and was widely used in commercial and industrial electronics.
Historical Note:
The RCA 2N4347 belongs to the era of American-made power semiconductors that were widely used during the late 1960s, 1970s, and early 1980s. RCA was one of the largest semiconductor manufacturers in the United States and supplied transistors for communications equipment, industrial controls, consumer electronics, and power supply applications. TO-3 devices from this period remain highly sought after for restoration and repair work.
