TIP41C NPN Power Transistor (TO-220)

Alongside the MJE3055, the TIP41C is one of the most frequently specified NPN power transistors in hobby and semi-professional audio and power electronics designs, offering a comfortable 6A rating in the standard TO-220 package. It pairs with its PNP complement, the TIP42C, in classic push-pull amplifier output stages, and stands in just as well on its own for medium-power motor and relay switching jobs. Its sheer ubiquity in existing schematics and tutorials makes it worth stocking alongside the MJE3055 as a second well-documented power transistor option.
