: Suitable for relay drivers and general-purpose high-voltage amplification. Modern Substitutions

(formally known as the ) is a high-voltage NPN silicon transistor originally manufactured by Sony and Hitachi, frequently found in classic audio equipment like Pioneer amplifiers. Finding a modern replacement requires careful attention to its unique combination of high voltage and power handling. Key Specifications (Datasheet Summary) c1124 transistor datasheet better

The C1124 transistor is a bipolar junction transistor (BJT) commonly used in electronic circuits due to its high current gain, low saturation voltage, and high switching speed. Understanding the datasheet of this transistor is crucial for designers and engineers to ensure optimal performance and reliability in their applications. Case Color : Original Sony units are often

| Substitute | Notes | |------------|-------| | 2SC3355 | Higher fT, lower noise, similar pinout (check first) | | 2SC2570 | Very similar, often direct drop-in | | MPSH10 | Slightly lower fT, but widely available | | BFR91 | For higher power applications | low saturation voltage

: When facing the front of the transistor with the pins pointing down, the standard pinout is Base, Collector, Emitter (from left to right). Case Color : Original Sony units are often identified by a distinctive colored plastic case. Applications and Complementary Pairs Audio Equipment
