TO-252 explained

TO-252, also known as DPAK^[1] or Decawatt Package, is a semiconductor package developed by Motorola^[2] for surface mounting on circuit boards.^[3] It represents a surface-mount^[4] variant of TO-251 package, and smaller variant of the D2PAK package. It is often used for high-power MOSFETs and voltage regulators.

Variants

Package can have 3 pins with 90mil pitch or 5 pins with pitch. The middle pin is usually connected to the tab. The middle pin is sometimes omitted.
