Transistor Bc547b Hfe

A bc547 is a general purpose small signal transistor fit for almost all types of circuit applications and therefore extensively used for making an unlimited range of electronic gadgets today. Bc547 is a npn transistor hence the collector and emitter will be left open reverse biased when the base pin is held at ground and will be closed forward biased when a signal is provided to base pin.
