MOSFET BC547 is an NPN Bipolar Junction Transistor and like all other transistors, BC 547 has three pins called the emitter, collector, and base respectively.

BC547 NPN Transistor is designed for use as general purpose amplifiers and switches requiring collector currents to 300 mA. Sourced from Process 10. See PN100A for characteristics. BC547 is a BJT transistor and is often used to satisfy the need of quick switching.

BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.

A Transistors acts as an Amplifier when operating in Active Region. It can amplify power, voltage and current at different configurations.

BC 547 NPN Transistor acts as a switch between the collector and emitter. If the base of the transistor is given enough current, this switch closes and the current flows from the collector to the emitter.

So a small current to the base pin of the transistor switches the large current between the collector and the emitter. BC547 is also used for the amplification of the input signals.

The main function of this NPN Transistor BC 547 is to amplify as well as switching purposes. The maximum gain current of this transistor is 800A.

In a forward bias mode, the two terminals like emitter & collector are connected to allow the flow of current through it. Whereas in a reverse bias mode, it doesn’t allow the flow of current through it because it works as an open switch.

The maximum amount of current that could flow through the Collector pin is 100mA. When this transistor is fully biased then it can allow a maximum of 100mA to flow across the collector and emitter.
