The BD680AG is a single bipolar junction transistor (BJT) that was released by STMicroelectronics. It is often used in the amplifying and switching applications of low-level analog circuits. This particular BJT has a powerful interstage amplifier, which makes it well suited for use in audio amplifiers, radio receivers, televisions, and other circuit designs.

The BD680AG is a medium-power small-signal transistor with a NPN structure. It is composed of three terminals: the emitter, the base, and the collector. The emitter and the collector pins form an enclosed junction called the base region. When a charge is present in the base region, it allows current to be conducted through the device. This process is known as the base drive current.

The BID680AG’s typical current gain is 40 at 1 mA; the cutoff frequency is 10 Mhz; the maximum DC current is 2 amps, and the maximum power dissipation is 1.5 W. It also features an encapsulated package, so that it can fit conveniently into a wide variety of printed circuit boards.

In order to take advantage of its many features, an understanding of the BD680AG’s specifications is necessary. Its characteristics include an operating voltage range of 4.5V to 12V for the collector-emitter voltage; a current gain of >270; a junction temperature range of -40°C to +125°C; and an average current gain of 40 at collector currents from 1 mA to 2 A. It is also suitable for operation up to 200 MHz.

The BD680AG is primarily used in audio amplifier circuits, radio receivers, and television circuitry. Its low noise and low distortion characteristics are ideal for these types of applications. In addition, it can be used as an amplifier or switch in low level analog and digital circuits, including precision instruments and high-precision temperature controls.

The BD680AG works by amplifying and switching an input signal that is applied to the base. The current gain, or β, is responsible for amplifying the input signal. When a current is applied to the base, the collector-emitter voltage will drop, creating a voltage gain. This voltage gain creates an amplified output which can then be used to activate transducers or perform other functions.

The BD680AG is a widely used transistor due to its many features and benefits. Its low noise and low distortion characteristics make it a great choice for audio amplifiers and other precision circuits. It is also very reliable, and is able to handle a large amount of current and power. The BD680AG is a great option for any circuit design requiring a single bipolar junction transistor.
