2SC5200-O(Q)

The 2SC5200-O(Q) is a type of bipolar junction transistor (BJT) that is commonly used in high-powered audio amplifier applications where high voltage and high current capabilities are needed. It is most often found in the output stages of high-powered audio amplifier systems, such as car audio systems, home theater systems, and PA systems. The 2SC5200-O(Q) has a collector current rating of 15A, which makes it suitable for higher power applications. It also has a high voltage rating of 125V, making it well suited for driving loudspeakers.

The 2SC5200-O(Q) is a NPN type device, meaning it works as an amplifier. When biased correctly with a base-emitter voltage of 0.7V, the transistor conducts current from the Collector to the Emitter region. This is known as the active region of the transistor, and it is in this region that it amplifies current. As current flows through the transistor, it switches from an "OFF" state to an "ON" state, allowing current to pass freely.

When the transistor is in the active region, it acts as a current amplifier. The gain of the amplifier is given in terms of the current gain of the device, known as the Beta value. The Beta value is the ratio of the current flowing in the collector-emitter path to the current flowing in the base-emitter path. Upon biasing the transistor with a base drive voltage, a small amount of current flows through the base-emitter junction. This causes more current to flow through the collector-emitter path and since the collector current is higher than the base current, the transistor operates with a gain.

The 2SC5200-O(Q) is highly capable for use in audio amplification applications. It offers high voltage and current ratings alongside a low saturation voltage, allowing it to accurately reproduce audio signals. The transistor is also well suited for applications that require a high level of power, such as car audio systems or home theatre systems. Due to its high current and low saturation voltage, the 2SC5200-O(Q) is an ideal choice for high-powered audio amplifier applications.

In conclusion, the 2SC5200-O(Q) is an ideal choice for high-power audio amplifier applications that require high voltage and current ratings. It has a high voltage rating of 125V and a collector current rating of 15A. The transistor is a NPN type and operates in the active region when correctly biased with a base-emitter voltage of 0.7V. The Beta value of the device determines the current gain of the amplifier and the low saturation voltage of the 2SC5200-O(Q) makes it well suited for audio applications.
