Motorola 454 Vintage TO-3 NPN Silicon Power Transistor
$19.99
Original Motorola 454 NPN silicon power transistor housed in the rugged TO-3 metal can package. This USA-made Motorola device has been professionally tested and verified functional with exceptionally high gain, extremely low saturation voltage, and no measurable collector leakage. Suitable for vintage electronics restoration, industrial controls, communications equipment, power supplies, amplifier circuits, power regulation systems, and semiconductor collections. The robust TO-3 package provides excellent thermal performance for demanding applications.
Historical Note:
Motorola was one of the world's leading semiconductor manufacturers throughout the 1960s, 1970s, and 1980s. Many Motorola TO-3 devices carried house numbers or OEM-specific markings for commercial, industrial, communications, and military equipment. These rugged power transistors earned a reputation for reliability and remain sought after by technicians restoring vintage electronic equipment.
