BC546B (116) is a type of single bipolar transistor commonly used in several electronic devices. This transistor has a collector current of up to 1.0A, collector-base voltage of up to 40V and an emitter-base voltage of up to 5V. It also has a power dissipation rating of 625mW and a low base-emitter voltage of 2V. The BC546B (116) belongs to the Transistors – Bipolar (BJT) – Single type. It is a three-terminal semiconductor device consisting of two p-type and one n-type layer. The two p-type layers are commonly known as the emitter and collector while the n-type layer is known as the base. The current flow between the emitter and collector is controlled by the base and the amount of current supplied to the base, the current gain known as hFE is determined by the circuit configuration.The BC546B (116) transistor includes a broad range of applications such as digital-to-analog and analog-to-digital converters, audio amplifiers and transceivers, voltage regulators, data display systems, digital logic gates, etc. This transistor can also be used in circuits as a switch or an amplifier.The working principle of BC546B (116) bipolar transistor revolves around the concept of the majority carrier current, which is the current that flows from the emitter to the collector. When the voltage applied to the base is increased, the transistor turns on and allows majority carrier currents to flow from the emitter to the collector. When the base voltage is decreased, the same currents will be reduced and the transistor will turn off.The BC546B (116) transistor is one of the most commonly used transistors in electronics today, owing to its wide range of applications and relatively low cost. Its excellent characteristics such as low power consumption, high-current gain, low voltage and current ratings, and low distortion make it ideal for a range of applications.
