WebIts main function is to pass the majority carriers from the emitter to the collector. This is indicated by the letter B. Collector. The right side material in the above figure can be understood as a Collector. Its name implies its function of collecting the carriers. This is a bit larger in size than emitter and base. It is moderately doped. WebThe minority carriers are constantly generated due to thermal energy so this state of equilibrium can be broken by raising the temperature of the PN junction causing an increase in the generation of minority carriers, thereby resulting in an increase in leakage current but an electric current cannot flow since no circuit has been connected to the …
