TO-220-3 Vertical

The TO-220-3 is the most iconic power semiconductor package in electronics. With three leads at 2.54mm pitch and a large metal tab for heatsink mounting, it handles up to 150W with proper cooling. This vertical mount variant is the standard footprint for the 7805/7812 voltage regulator family, LM317 adjustable regulator, IRF520/IRF540 power MOSFETs, and TIP31/TIP41 power transistors. The through-hole mounting provides excellent mechanical stability and thermal connection to heatsinks or copper planes.
