Darlington Transistors

A Darlington transistor contains two BJT transistors coupled to act as a single transistor with a much higher current gain. This means that the tiny current from a sensor or microcontroller I/O pin can be amplified to drive a large load. These devices are also known as Darlington Pairs and are made in standard 3-pin package formats. Darlington transistors are also manufactured in packages containing seven or more devices, each with protection diodes, for the purpose of driving inductive loads (e.g. DC motors) from microcontroller GPIO pins.
