These values represent the physical limits of the transistor. Exceeding them will cause permanent damage to the component. 150 V Collector-Emitter Voltage ( VCEOcap V sub cap C cap E cap O end-sub ): 150 V Emitter-Base Voltage ( VEBOcap V sub cap E cap B cap O end-sub ): 5 V Collector Current ( ICcap I sub cap C ): 50 mA (Continuous) Collector Power Dissipation ( PCcap P sub cap C ): 1 W (at a ambient temperature of 25°C) Junction Temperature ( Tjcap T sub j ): 150°C Electrical Characteristics
Decoding the C1124 Transistor Datasheet: Specifications, Applications, and Modern Equivalents
If you search for a replacement using just the part number, you might stumble upon an equivalent list, but you won't know one transistor is a better choice than another. Understanding the datasheet allows you to make an informed decision. You need to find a modern transistor whose Absolute Maximum Ratings are equal to or greater than those of the 2SC1124 and whose Electrical Characteristics are similar enough to function correctly in the circuit. c1124 transistor datasheet better
Whether you require a for a push-pull topology.
If you want, I can draft a short forum/social media post version or fetch the exact manufacturer datasheet PDF. These values represent the physical limits of the transistor
If an original 2SC1124 is unavailable, high-quality alternatives like the OnSemi KSC2690A
and 1A collector current in a TO-202/TO-220 package. Commonly paired with the 2SA706 for Class AB amplifiers, this transistor offers high linearity and thermal stability, with common alternatives including 2SC1162 and 2SC5200. Detailed specifications and application data are available from UXPython and AllTransistors . Understanding the datasheet allows you to make an
The 2SC1124 (often abbreviated as C1124) is a classic NPN epitaxial planar silicon transistor designed primarily for high-voltage applications, such as video output stages in televisions, audio amplifiers, and high-frequency switching circuits. Finding a "better" datasheet for this legacy component means locating documentation that provides high-clarity characteristic curves, precise thermal parameters, and explicit safe operating area (SOA) graphs.
