577202B00000G Description

Short technical summary and product information.

The 577202B00000G is a board level heat sink designed for cooling TO-220 semiconductor packages. It is constructed from aluminum with a black anodized material finish, providing corrosion resistance and improved thermal emissivity. The heat sink has a rectangular shape with fins, measuring 19.05mm in length, 13.21mm in width, and a fin height of 12.70mm (0.500"). Attachment is via bolt-on mounting, making it suitable for permanent or semi-permanent installation.

 

Thermal performance is specified at 24.40°C/W under natural convection and 10.00°C/W at 200 LFM forced air flow, demonstrating significant improvement with active cooling. The heat sink can dissipate up to 1.5W at a 40°C temperature rise. This makes it appropriate for low-to-moderate power applications where TO-220 devices require thermal management in confined spaces.
