![]() ![]() always.) hence, the “saturation” voltage of a Darlington transistor is one (VBE) (about 0.65 V in silicon) higher than a single transistor saturation voltage, which is commonly 0.1 – 0.2 V in silicon. The Darlington Transistor comprises two PNP or NPN transistors coupled to each other in a back-to-back configuration. The Bipolar Junction Transistor (BJT) as a Switch NPN Transistor: Application and Circuit Working. However, there are two junctions between the base and emitter of the Darlington transistor, the equal base-emitter voltage is the sum of both base-emitter voltages: One defect is an approximate doubling of the base-to-emitter voltage.The Darlington Pair transistor can be simply made with two different NPN transistors, and it is also available in the kinds of single packages. It can be designed easily, it’s also an advantage.Another advantage involves providing a very high input impedance for the circuit, which also translates to an equal decrease in output impedance.A common Darlington transistor has a current advantage of 1000 or more, however, only a small base current is needed to make the pair switch on higher switching currents.The pin configuration of Darlington Pair transistor. The Darlington Pair may sometimes also be referred to as a super-alpha pair, however, this name is used less these days and the circuit configuration was invented at Bell Laboratories by Sidney Darlington in 1953. Nevertheless, where applicable, the Darlington Pair is able to provide many gains over a single transistor circuit configuration. I am using the Arduino Mega 2560 as a controller to turn on/off a 5/2 way air solenoid valve. ![]() However, the Darlington Pair does have some defects and it is not suitable for all high-gain applications as a result. Darlington transistor as a switch for solenoid control valve Using Arduino General Electronics edarby June 13, 2022, 5:08pm 1 Hi there, Extremely new to electronics and am getting confused with information online about this. It is fundamentally used because it offers especially high gain and this also reflects in a high input impedance for the overall Darlington circuit when compared to a single transistor. The Darlington Pair provides a number of advantages. One transistor circuit configuration which can be used to quite a good effect in many instances is the Darlington Pair. The Darlington Pair transistor configuration of two bipolar transistors offers growth current switching for a given base. In this configuration the Darlington Transistor provide high gain ability.
