RCA FBN36220 NPN Silicon Power Transistor TO-3 Bench Tested Pull

Original RCA FBN36220 NPN silicon power transistor housed in the classic TO-3 metal package. This bench-tested device is suitable for restoration, repair, replacement, and vintage electronics projects requiring a high-reliability NPN power transistor. The rugged TO-3 package was widely used in communications equipment, industrial controls, power supplies, audio amplifiers, test equipment, and military-grade electronics. This RCA device demonstrated strong gain, exceptionally low saturation voltage, and zero measurable leakage during RF Boneyard™ bench testing, making it an excellent candidate for restoration work and vintage equipment repairs.
The RCA FBN series power transistors were produced during the golden era of American semiconductor manufacturing when metal-can TO-3 devices dominated industrial and commercial electronics. RCA was one of the most respected semiconductor manufacturers of the period, supplying devices used in communications systems, laboratory equipment, power regulation circuits, and audio amplifiers. Original RCA TO-3 transistors remain desirable among restorers because many vintage designs were engineered and qualified around these American-made components.
