The TIP3055 is a high-power NPN transistor used in amplifiers, regulators, and motor drivers, handling up to 15 A and 60 V.
Pinout (TO-247/TO-218): 1-Base, 2-Collector, 3-Emitter (collector is also connected to the metal tab).
It offers good gain and speed, making it ideal for both linear and switching applications.
