In a forward bias mode, the two terminals like emitter & collector are connected to allow the flow of current through it. The working states of BC547 transistor include the following. The amplifier circuit uses three configurations which include the following.įrom the above three configurations, CE is the most widely used configuration. Pin3 (Emitter): The current supplies out through emitter terminalĪ Transistor works as an amplifier while functions in the active region to amplify voltage, current, and power at various configurations.Pin2 (Base): This pin controls the transistor biasing.Pin1 (Collector): This pin is denoted with symbol ‘C’ and the flow of current will be through the collector terminal.The BC547 transistor includes three pins which include the following.
