Darlington Pair Pnp. In the below images two type of darlington transistor are shown. It can handle up to 5a continuously with bursts of 8a and up to 60v across the collector and emitter.
An npn darlington will have two npn transistors connected as shown below and a pnp device will use two pnp transistors. Darlington transistor pair and its configuration. The darlington pair circuit finds many applications as the series pass element in a linear regulator.
Cc by sa 3 0 by wikipedia user michael9422 a common darlington pair is the tip120 which is a great choice for the examples later in this guide.
Sziklai transistor pair and its configuration. 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. There is no much difference in the circuit using npn or pnp. At its core a darlington pair is simply two transistors cascaded together.
