Why is the base current in a transistor very small?

The base collected junction a transistor is reverse biased. Hence more than 98% of emitter current reaches the collector. A very small amount of charge carriers do not reach the collector and flows into the base circuit constituting base current ( less than 2%).

FAQ

What is Base current when saturation current in DC is given?
The Base current when saturation current in DC is given a common-base (also known as grounded-base) amplifier is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a current buffer or voltage amplifier and is represented as IB=(Is/β )*e^(VBE/Vt)+es*e^(VBC/Vt) or Base Current=(Saturation current/Common emitter current gain)*e^(Voltage across the base–emitter junction/Thermal voltage)+Saturation Vapour Pressure at Water Surface*e^(Voltage across base-collector junction/Thermal voltage). Saturation current is the diode leakage current density in the absence of light. It is an important parameter which differentiates one diode from another, Common emitter current gain is highly influenced by two factors: the width of the base region, W, and the relative dopings of the base region and the emitter region, The voltage across the base–emitter junction is the forward voltage between the base and emitter of the transistor, Thermal Voltage is the voltage produced within the p-n junction, Saturation Vapour Pressure at Water Surface (mm of mercury) and Voltage across base-collector junction is the electric potential between the base and collector region of a transistor.
