TO-252
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. Variants 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.

TO-263
The Double Decawatt Package, D2PAK, SOT404 or DDPAK, standardized as TO-263, refers to a semiconductor package type intended for surface mounting on circuit boards. The TO-263 is designed by Motorola. They are similar to the earlier TO-220-style packages intended for high power dissipation but lack the extended metal tab and mounting hole, while representing a larger version of the TO-252, also known as DPAK, SMT package. As with all SMT packages, the pins on a D2PAK are bent to lie against the PCB surface. The TO-263 can have 3 to 7 terminals. Image:D2PAK.JPG, A pair of MOSFETs in the surface-mount package D2PAK.

The height of the TO-263 THIN is 2mm instead of the standard 4,5mm. See also TO-220, through hole version of the TO-263 References External links Package informationfrom Fairchild Mechanic ...
