Working Principle

The BC856B-TP transistor works on the same principle as other transistors. It is made up of three layers: the Emitter, Base and Collector. Electric current flows between two regions, the emitter and collector and is controlled by a third region, the base. When a current flows through the base, the voltage at the base and emitter region, causes a current to flow from the emitter to the collector, which increases the current through the collector. The greater the current through the collector the larger the gain of the transistor.The voltage across the collector and emitter region determines the type of current. If the voltage is greater than the base-emitter voltage (Vbe), then the transistor will be saturated and the collector current will be increased. If the voltage is less than the base-emitter voltage (Vbe), then the transistor will be in cutoff mode and the current through the collector will be reduced.The gain of the transistor is the ratio of the collector current to the base current. The higher the current gain, the better the performance of the transistor. The current gain of the BC856B-TP is typically between 250 and 500.
