C1124 Transistor Datasheet Better |top| -

Could you tell me (e.g., vintage stereo amplifier, linear power supply, or monitor) you are repairing or modifying? Knowing the surrounding components and operating voltages will help me recommend the exact substitute that best fits your needs! 2SC1124 Transistor - Buy from Littlediode

The 2SC1124 (C1124) is a high-performance NPN BJT designed for high-fidelity audio, featuring 160V VCBOcap V sub cap C cap B cap O end-sub

: Typically found in the TO-202 or similar power packages designed for heat sink mounting.

Because original stock is increasingly rare and subject to counterfeit or degraded parts, reading and understanding the is vital to securing a better, safer, and more reliable alternative for your circuit. 1. Key Technical Specifications

Imagine you are repairing a 1985 Kenwood amplifier that uses four C1124 transistors in the voltage regulator. c1124 transistor datasheet better

: A modern, widely available high-voltage NPN transistor (often in TO-126) used for similar video/high-voltage tasks. BF459 : Another common video output transistor.

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.

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

The essential metrics from the official Littlediode 2SC1124 Data Sheet include: : NPN Material : Silicon (Si) Maximum Collector-Base Voltage ( VCBOcap V sub cap C cap B cap O end-sub ) : 160 V Maximum Collector-Emitter Voltage ( VCEOcap V sub cap C cap E cap O end-sub ) : 140 V Maximum Emitter-Base Voltage ( VEBOcap V sub cap E cap B cap O end-sub ) : 5 V Maximum Continuous Collector Current ( ICcap I sub cap C ) : 1 A (1000 mA) Maximum Collector Power Dissipation ( PCcap P sub cap C Could you tell me (e

The original C1124 sometimes has a non-isolated tab. Modern replacements (like TIP31C) have a collector-connected tab. If your heatsink is grounded, you must use a mica insulator.

: The 100 MHz transition frequency indicates it can handle rapid signal changes, making it efficient for switching power supplies. Thermal Management : In high-power circuits, it requires a heat sink. Proper soldering and mounting techniques are critical to prevent thermal runaway. Common Substitutes and Equivalents

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 .

Great for medium-power amplifier stages and power supply regulators. Note that the VCEOcap V sub cap C cap E cap O end-sub is slightly lower than the , so verify your circuit doesn't exceed 120 V rail-to-rail. Crucial Considerations When Installing Substitutes Because original stock is increasingly rare and subject

While it's surprisingly difficult to find the original, official Sony datasheet today, reliable aggregate sources provide the core specifications that define the component's capabilities. The table below offers a detailed breakdown of the 2SC1124's absolute maximum ratings and electrical characteristics:

Here is what defines a replacement:

Keep in mind that the C1124 transistor is a Chinese-made device, and its quality and reliability might vary depending on the manufacturer.
