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.
Package can have 3 pins with 90 mils (2.3 mm) pitch or 5 pins with 45 mils (1.1 mm) pitch.
The middle pin is usually connected to the tab.
