TO:220

The TO-220 (Transistor Outline 220) is a through-hole package designed for power semiconductor applications. Featuring a standard three-lead configuration, an integrated metal tab for heatsink mounting, and a robust vertical mounting design, it delivers superior heat dissipation and high current handling capability. Typical dimensions are 10.16 mm × 15.75 mm (width × length) with a 2.54 mm pin pitch and a height of approximately 4.7 mm, making it ideal for power regulators, power transistors, and linear voltage regulators. Its exposed metal backplate enables direct thermal transfer to heatsinks, while RoHS-compliant materials ensure reliability in industrial environments.
