达灵顿晶体管（英语：Darlington transistor），或称达灵顿对（Darlington pair）是电子学中由两个（甚至多个）双极性晶体管（或者其他类似的集成电路或分立组件）组成的复合结构，通过这样的结构，经第一个双极性晶体管放大的电流可以进一步被放大。这样的结构可以提供一个比其中任意一个双极性晶体管高得多的电流增益。在使用集成电流芯片的情况里，达灵顿晶体管可以使得芯片比使用两个分立晶体管组件占用更少的空间，因为两个晶体管可以共用一个集极。达灵顿晶体管通常被封装在单一的芯片里，从外面看就像一个双极性晶体管。有时，集成电路芯片中会包含8个这样的结构方便使用。

In electronics, the Darlington transistor (often called a Darlington pair) is a compound structure consisting of two bipolar transistors (either integrated or separated devices) connected in such a way that the current amplified by the first transistor is amplified further by the second one. This configuration gives a much higher current gain than each transistor taken separately and, in the case of integrated devices, can take less space than two individual transistors because they can use a shared collector. Integrated Darlington pairs come packaged singly in transistor-like packages or as an array of devices (usually eight) in an integrated circuit.
