7109DG Description

Short technical summary and product information.

The 7109DG is a top mount heat sink designed for TO-263 (D²Pak) packages. It features a rectangular finned shape and is constructed from copper with a tin finish. The heat sink measures 19.38mm in length and 25.40mm in width, with a fin height of 11.43mm (0.450").

 

Thermal performance is rated at 11.00°C/W under natural convection and 3.00°C/W at 300 LFM forced air flow. It can dissipate 2.0W at a 30°C temperature rise. The attachment method is an SMD pad, making it suitable for surface mount applications.

 

This heat sink is intended for use with TO-263 (D²Pak) packages, providing a compact thermal management solution for power devices. The copper construction offers good thermal conductivity, while the tin finish provides a solderable surface for SMD mounting.
