The TIP31 is a standard NPN bipolar junction transistor that is often used for medium power applications. A bipolar
junction transistor (BJT) is a three terminal device that is allows for amplification or switching applications. Some transistors can amplify a small current which will then be powerful enough to operate a lamp or other high current devices. These devices are also able to detect a change in voltage act as a switch
