A TO-220 package compared to a D2PAK package
The D2PAK or DDPAK, standardized as TO-263, refers to a semiconductor package type intended for surface mounting on circuit boards. They are similar to the earlier TO-220-style packages intended for high power dissipation but lack the extended metal tab and mounting hole, and also represent a larger version of the DPAK SMT package. As with all SMT packages, the pins on a D2PAK are bent to lie against the PCB surface.
