In addition, they can be used in power supplies, such as switched mode power supplies, AC-DC converters, and LCD displays.

• Working Principle

BC547C, 126 transistors work by controlling the amount of current that flows through the device. The device consists of three terminals—the base, collector, and emitter – and operates using the principle of current biasing.When a voltage is applied to the base terminal, it creates an electric field across the device’s layers, which generates a collector current. This collector current is the current that flows from the collector to the emitter, which is known as the collector-emitter current. This process is known as “biasing” and is used to control the device’s output.When the base voltage is increased, it increases the collector current and the transistor is said to be “turned on.” As the base voltage is decreased, the collector current decreases and the transistor is said to be “turned off.” This action is used to control the flow of current through a circuit, allowing users to switch on and off components in a circuit or to control the amount of current that flows through the device.

• Conclusion

BC547C, 126 transistors are popularly used in a wide variety of applications, including amplifying and switching signals in industrial and consumer devices, as well as power control, lighting, and monitoring in automotive applications. They are also used in home and office automation, audio equipment, and power supplies. Their operation is based on the principle of current biasing, whereby the current through the device is controlled by the voltage applied to the base terminal. With this information, it is easy to understand how this transistor is used in various applications.
