2N5680 is an NPN silicon pre-biased transistor, which is specifically designed for use in audio amplifiers and driver applications. It is a dual-gate Darlington-structure transistor, with a nominal breakdown voltage of 70V and a continuous collector current rating of 7.5A. It is available in an eight-pin TO-220 package.

2N5680 application field lies mainly in audio amplifiers, driver applications, and wide band communication systems. It is suitable for low-noise and high fidelity audio amplifiers, especially for driving small speakers. In addition, it is also used for motor control and driver applications. 2N5680 can also be applied in wide band communication systems, like short-wave and high-frequency amplifiers of communication systems.

The working principle of 2N5680 involves the collector current amplification by the Darlington structure. The two gates of the transistor are connected in series, which allows the transistor to act as an amplifier with a slight voltage drop across the two gates. As the input voltage increases, the current flow through the two gates of the Darlington structure is increased. This increase in current is reflected as an increase in collector current, which enables the transistor to operate as an amplifier.

2N5680 has become very popular in the audio amplifier and driver applications due to its low noise, low cost, and high gain. It is also used in many other electronic devices and systems, such as motor control systems, automotive applications, power supplies, oscillators, and digital circuits. Furthermore, it can be used in many more recent applications such as robotics and VLSI circuits.

2N5680 is designed as an audio amplifier and driver applications transistor, offering high current gain and a low voltage drop across the device. Its dual-gate Darlington structure also enables the transistor to operate as an amplifier, while the low-noise performance makes it suitable for audio amplifier applications. In addition, it is a cost-effective option for many other applications due to its excellent performance and reliability.
