TO-220
The TO-220 is a style of electronic Semiconductor package, package used for Power semiconductor device, high-powered, Through-hole technology, through-hole components with pin spacing. The "TO" designation stands for "transistor outline". TO-220 packages have three leads. Similar packages with two, four, five or seven leads are also manufactured. A notable characteristic is a metal tab with a hole, used to mount the case to a heatsink, allowing the component to dissipate more heat than one constructed in a TO-92 case. Common TO-220-packaged components include discrete semiconductors such as transistors and silicon-controlled rectifiers, as well as integrated circuits. Typical applications The TO-220 package is a "power package" intended for Power semiconductor device, power semiconductors and an example of a through-hole design rather than a surface-mount technology type of package. TO-220 packages can be mounted to a heat sink to dissipate several watts of waste heat. On a so- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
