Westinghouse 2N4348 NPN Silicon Power Transistor TO-3 Metal Can Bench Tested
$19.95
Original Westinghouse 2N4348 NPN silicon power transistor housed in the classic TO-3 metal can package. This vintage USA-manufactured semiconductor features the recognizable Westinghouse "W" logo and has been individually bench tested by RF Boneyard™.
The 2N4348 was commonly used in power supply assemblies, industrial control equipment, amplifier circuits, laboratory equipment, and other applications requiring a rugged TO-3 power transistor. Bench testing verified gain, junction integrity, saturation voltage, and collector leakage performance.
A great candidate for vintage electronics restoration, repair inventory, engineering evaluation, semiconductor collections, and replacement applications where compatibility has been confirmed by the buyer.
