A Darlignton pair is two transistors that act as a single transistor providing high current gain. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. These materials may be available by special order, in distribution inventory, or reinstated as an active product.

In this pair the current amplified by the first transistor is further amplified by the next transistor providing high current to the output terminal.
