TO-263 explained

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. They are similar to the earlier TO-220-style packages intended for high power dissipation^[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.

Variants

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.^[5]
