Working principle
The DTC114ECAHZGT116 is a two-terminal, pre-biased bipolar transistor. In its active mode, the transistor relies on two p-n junctions as the core components. The junctions act as a current switch and controls the internal current flow between the collector and emitter terminals.
First, the base current (IB) is fed from the external circuit to the base terminal, which controls the collector-emitter current (IC). As the input base current increases, the current flowing through the collector and emitter is also increased. At the same time, the voltage between the collector and emitter terminals (VCE) decreases, indicating an increase in the transistor’s gain. This phenomenon is known as biasing, and it is necessary for the correct operation of the transistor.
Second, when the collector-emitter voltage is biased, the transistor becomes saturated, and the base current controls the collector-emitter current (IC). This is the active mode of the transistor. When the collector current is increased, the voltage across the collector-emitter terminals decreases, indicating an increased current gain. This is a form of feedback, as the collector current is both controlling the gain of the transistor and being controlled by the base current.
Finally, when the base current is removed, the collector-emitter voltage returns to its original level, and the base current no longer controls the collector current. This is the off mode of the transistor, where the collector-emitter voltage is not biased and the transistor operates at its normal gain.
