Darlington Transistor Configuration

Normally to turn on a transistor the base input voltage of the transistor will need to be greater than 07v. Therefore the base voltage will need to be greater than 07v x 2 14v.

It normally consists of two transistors although in theory it can contain more.

Darlington transistor configuration. The emitter of the input transistor is connected directly to the base of the second. It acts as the input of the second transistor. The max ce voltage of darlington transistor is 450v and power dissipation can be in the range of 200mw to 250mw.

A darlington transistor is a back to back connection of two transistors that comes as a complete package with three leads base emitter and collector as equivalent to the single transistor. Darlington transistor in electronics a multi transistor configuration called the darlington configuration commonly called a darlington pair is a compound structure of a particular design made by two bipolar transistors connected in such a way that the current amplified by the first transistor is amplified further by the second one. 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 tr 1 becomes the base current of the second transistor tr 2.

Darlington transistor uses two standard bjt bi polar junction transistor transistors which are connected together. Darlington transistor or darlington pair. In contrast to the darlington arrangement the complementary feedback pair has one npn and one pnp transistor and so it is sometimes also called the complementary darlington.

Both collectors are connected together. Then the transistor t1 is connected as an emitter follower and transistor t2 as a common emitter amplifier. So that the emitter terminal in which the current is produced its been provided to the base of the second transistor.

The common values of max ce voltage are 30v 60v 80v 100v. The darlington pair circuit configuration is quite distinctive. In electronics the complementary feedback pair also known as a sziklai pair is a configuration of two bipolar transistors similar to a darlington pair.

Darlington transistors are classified into different types by power dissipation max ce voltage polarity min dc current gain and type of packaging. Darlington transistor configuration is also known as darlington pair or super alpha circuit. As two transistors are used in a darlington pair this value is doubled.

Into this the two npn transistors or pnp transistors are connected together in such a way so that the emitter current of the first transistor t1 become the base current of the second transistor t2. This configuration is called as darlington transistor configuration. Darlington transistor connected in a configuration where one of transistors emitter provides biased current to the other transistors base.

The configuration is named for its early popularizer george c. Basic darlington transistor configuration let us consider two n p n transistors connected through their respective collectors.
