531102B02500G Description

Short technical summary and product information.

The 531102B02500G is a board level vertical heatsink designed for cooling TO-220 semiconductor packages. Manufactured by Aavid, Thermal Division of Boyd Corporation, this heatsink features a rectangular finned shape constructed from aluminum with a black anodized finish for enhanced thermal performance and corrosion resistance.

 

With dimensions of 38.10mm (1.500") length, 34.93mm (1.375") width, and 12.70mm (0.500") fin height, this heatsink provides a natural convection thermal resistance of 10.40°C/W. Under forced air flow of 500 LFM, thermal resistance drops to 3.00°C/W, enabling power dissipation of 7.0W at a 70°C temperature rise.

 

The attachment method combines bolt-on and PC pin mounting, making it suitable for secure installation on printed circuit boards. The vertical orientation optimizes airflow in convection and forced air environments.
