This document provides information about the mechanical outline drawing, thermal curves, and thermal resistance value of the product 7109DG, which is designed for Surface Mount packages. The product is a surface mount heat sink for D2 Pak (TO-263) package semiconductors, with a matte tin plated finish. It is packaged in tape and reel for automated assembly. If a more unique solution is required, slight modifications or other attachment options, finishes, and interface materials can be chosen by contacting the local representative of Aavid. Custom solutions can also be designed based on thermal requirements.
The 7109DG is a surface‑mount heat sink offered by Aavid Thermalloy. It is supplied in tape‑and‑reel packaging for automated assembly and is designed to withstand standard soldering and reflow processes without affecting its performance.
The document includes a mechanical outline drawing, thermal curves, and recommended copper pad dimensions. It also lists the part number, package type (TO‑263), finish (Matte Tin), and thermal resistance based on a 75 °C rise in natural convection.
