TIP120 Darlington Transistor TO-220 NPN ST Arduino Supply DIP IC AH51
The TIP120 is a NPN darlington transistor with a current gain of 1000 making it the ideal choice for interfacing many higher current or higher voltage loads to a microcontroller or Raspberry Pi. It can be used to control DC motors, solenoids or high-power LEDs up to 2W without using a heat sink.
