TIP122 is a general-purpose NPN transistor with high voltage and current. This Darlington transistor is used in general amplification and a low-speed switching circuit. It is a normal transistor expect Darlington pair inside, because of that its collector current rating is about 5A and gain 1000V. It has a 5V base-emitter voltage which can be directly controlled by a logic level device like controllers.
