3D model of TO-263AA package
The Double Decawatt Package,[1][2] D2PAK, SOT404 or DDPAK, standardized as TO-263,[3] is a semiconductor package type intended for surface mounting on circuit boards. The TO-263 is designed by Motorola.[1][2] They are similar to the earlier TO-220-style packages intended for high power dissipation[2][4] 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.[1][2]

Variants
[edit]Texas instruments has a smaller version of the TO-263: the TO-263 THIN. The height of the TO-263 THIN is 2 mm instead of the standard 4.5 mm.[2][5]
