C1124 Transistor Datasheet Better _top_ Jun 2026

However, over decades of use, these transistors became known among audio restorers as "known baddies". Due to their high-heat operating environment, they often developed internal leakage or "silver whiskers," leading to "popping" noises in audio or total channel failure. Finding a "better" datasheet today usually means finding a modern replacement that can handle the heat better than the original Technical Specifications According to modern archives and retailers like Lee's Electronic Components LittleDiode , the standard ratings are: Collector-Base Voltage ( cap V sub cap C cap B cap O end-sub Collector-Emitter Voltage ( cap V sub cap C cap E cap O end-sub Collector Current ( cap I sub cap C Power Dissipation ( cap P sub cap C 5 W (up to 7.9W in some conditions) Transition Frequency ( f sub cap T 120–140 MHz Package Type Modern "Better" Alternatives

: Positioned right before the heavy-duty power output transistors (like the 2SC5200 ), the C1124 acts as a voltage amplifier to cleanly boost incoming audio signals.

Based on the datasheet comparison, here are some observations: This link or copies made by others cannot be deleted

Whether you require a for a push-pull topology.

The (commonly designated as 2SC1124 ) is a classic NPN epitaxial silicon transistor packaged in a TO-5 or TO-39 metal can . Primarily designed for high-voltage audio amplifiers and television video output stages, it remains a component of interest for repair technicians, audio hobbyists, and hardware engineers.
