What is a Darlington transistor used for?

Darlington transistors are mainly used in switching and amplification applications for delivering a very high DC current gain. Some of the key applications are high and low side switches, sensor amplifiers and audio amplifiers.

What is a Darlington power transistor?

In electronics, a multi-transistor configuration called the Darlington configuration (commonly called a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further …

What is another name for a Darlington transistor?

A Darlington Transistor configuration, also known as a “Darlington pair” or “super-alpha circuit”, consist of two NPN or PNP transistors connected together so that the emitter current of the first transistor TR1 becomes the base current of the second transistor TR2.

What is the advantage of photo Darlington transistor?

➨It offers very high current gain in comparison to single transistor. ➨It offers very high input impedance. ➨It uses few components and hence can be used for easy circuit designs. ➨It can amplify signal to larger extent.

Why do we need Darlington pair?

Benefits or advantages of Darlington transistor ➨It offers very high current gain in comparison to single transistor. ➨It offers very high input impedance. ➨It uses few components and hence can be used for easy circuit designs. ➨It can amplify signal to larger extent.

What is the gain of Darlington transistor pair?

10 000
A typical Darlington pair has a gain of 10 000, and some have gains up to 50 000. A Darlington pair may be assembled from two individual transistors but it is more convenient to use a Darlington transistor.

What is advantage of Darlington connection?

Is a Darlington pair a current amplifier?

Applications of Darlington pair amplifier We already have seen that the Darlington pair amplifier circuit can provide a huge current gain. So, it has a wide range of use as a current Amplifier.
