TIP120 TO-220 Darlington Complementary Silicon Power Transistors

The TIP  120 is a NPN  darlington transistor with a current gain of 1000 that is a good choice for interfacing many higher current or higher voltage loads to an Arduino or other microcontroller. It can be used to control DC motors, solenoids or strings of LEDs with minimal current draw from the microcontroller.
