Considering this, how does a Darlington pair transistor work?
How A Darlington Pair Transistor Works. ADarlington pair is two transistors that act as a singletransistor but with a much higher current gain. This meanthat a tiny amount of current from a sensor, micro-controller orsimilar can be used to drive a larger load.
Secondly, what is meant by current gain? The current gain for the common-baseconfiguration is defined as the change in collector currentdivided by the change in emitter current when thebase-to-collector voltage is constant. Typical common-basecurrent gain in a well-designed bipolar transistor is veryclose to unity.
Also asked, what is the advantage of a Darlington pair?
The Darlington Pair offers a number ofadvantages. It is primarily used because it offers aparticularly high current gain and this also reflects into a highinput impedance for the overall Darlington circuit whencompared to a single transistor.
What is complementary transistor?
Transistor Matching A pair of corresponding NPN and PNP transistorswith near identical characteristics to each other are calledComplementary Transistors for example, a TIP3055 (NPNtransistor) and the TIP2955 (PNP transistor) are goodexamples of complementary or matched pair silicon powertransistors.
