C1124 Transistor Datasheet Better
): Ensure the replacement transistor falls within the same gain grouping (typically designated by letters like O, Y, P, or G on Japanese transistors) to prevent biasing imbalances in push-pull amplifier circuits.
The full part number is , with common variants including 2SC1124-1 , 2SC1124-3 , and sometimes it appears simply as C1124 on the component itself. This transistor uses a silicon (Si) semiconductor material. As an NPN bipolar junction transistor (BJT), it works in a configuration where a positive layer is sandwiched between two negative layers to create its three terminals: the Base , Collector , and Emitter .

The C1124 is housed in a standard, through-hole plastic package—most commonly the TO-126 (also known as the Up-To-2 package variant by some Japanese manufacturers) or the slightly modified TO-92MOD depending on the specific suffix and production era. Its physical construction features a centrally located collector tab or lead designed to optimize heat dissipation to an external sink. Key Features
The 2SC1124 is frequently found in the driver stage of vintage Japanese amplifiers (Pioneer, Sansui). When replacing, always check the hFE (Gain) grouping to match the original circuit's bias. ): Ensure the replacement transistor falls within the
The is a vintage, high-performance NPN silicon epitaxial planar bipolar junction transistor (BJT) originally manufactured by major electronics companies like Sony and Toshiba . Widely recognized in the repair and restoration community, this component is prominently featured in classic high-fidelity audio gear—such as the pre-driver stages of the iconic Pioneer SX-828 receiver —as well as vintage radio frequency (RF) equipment.
These are the "do not cross" lines. Operating the transistor beyond these values, even for a moment, can instantly destroy it. As an NPN bipolar junction transistor (BJT), it
: Utilized as a small-signal oscillator or signal booster in legacy communication devices.
