The BD680 is an NPN transistor fabricated with a low-cost silicon material, intended for use as an amplifier in audio circuits (mainly pre-amplifiers). This transistor is usually housed in the TO-126 package and consists of three terminals: collector, base, and emitter. It operates in the amplification region and is designed for high power applications.The BD680 transistor is a bipolar junction transistor (BJT), more specifically a single-transistor device. BJT transistors are two-terminal semiconductor devices that allow the current flow between the two terminals to be switched on and off, based on an input signal applied across the base and emitter terminals. Unlike MOSFETs (Metal Oxide Semiconductor Field Effect Transistor), BJTs are three-terminal devices, with the third terminal being the collector.This transistor is normally used to amplify electronic signals. It is known for its capability to provide high current gain (typically Amplified Current/Base Current, or hFE) with low impedance and low voltage drop (Vce) from collector to emitter. This makes them ideal for use in high-power applications, where current gain and low power dissipation are desired.The application field for the BD680 transistor includes switching, amplification and general purpose applications in both linear and non-linear circuits. The transistor is capable of providing high current gain (between 500 and 1000) and low power dissipation even at high voltages (up to 400V). Its maximum power dissipation of 85W makes it suitable for use in high-power applications such as audio amplifiers. The transistor has a forward transition frequency of 100 MHz, which makes it suitable for use in audio frequency circuits. The working principle behind the BD680 transistor is based on the current flow between the emitter and the collector. When a small current is sent to the base of the transistor, it amplifies the current to a much higher level, providing a much higher current gain. This is known as current amplification. This is opposed to voltage amplification, which is achieved by increasing the voltage across the transistor.The BD680 is an NPN transistor, which means it is polarized such that the collector can only accept current when the base is forward biased. This configuration is useful for amplifying high frequencies, as the transistor can switch faster than a PNP device. Conversely, PNP transistors are ideal for amplifying low frequencies, since they can switch slower than an NPN device.When configured properly, the BD680 can amplify a signal to a range up to 400V, which makes it ideal for use in audio frequency circuits. This transistor is also capable of providing high current gain (hFE) and low power dissipation. This makes it especially suitable for use in high power applications, such as audio amplifiers.Overall, the BD680 transistor is a versatile, high-performance transistor, suitable for use in a wide range of applications. Its ability to provide high current gain and low power dissipation makes it ideal for use in high-power applications, while its low forward transition frequency makes it ideal for use in audio frequency circuits. Its wide range of applications, coupled with its high reliability and availability, make the BD680 an attractive and cost-effective solution for many high-power circuits.
