TIP3055 Transistor NPN TRANSISTOR 3055 ST TIP3055

Product Overview

The TIP3055 is a high-power NPN silicon transistor designed for general-purpose switching and amplification. It is the plastic-packaged (TO-218/TO-247) version of the legendary 2N3055 metal-can transistor. Due to its high current handling and rugged design, it is a staple in linear power amplifiers, high-current voltage regulators, and switching power supplies. It is the NPN counterpart to the TIP2955.
