TO-252, also known as DPAK or Decawatt Package, is a semiconductor package developed by Motorola for surface mounting on circuit boards. It represents a surface-mount 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 pitch or 5 pins with pitch. The middle pin is usually connected to the tab. The middle pin is sometimes omitted.
