The Aavid 577202B04000G is a compact board-level heat sink designed for cooling TO-220 power packages. It features a rectangular finned shape with a height of 0.500" (12.70mm), width of 13.21mm, and length of 19.05mm, making it suitable for space-constrained applications. The heat sink is constructed from black anodized aluminum for enhanced thermal emissivity and corrosion resistance.
Thermal performance includes a typical thermal resistance of 24.4°C/W under natural convection and 10.0°C/W at 200 LFM forced airflow. The power dissipation capability is 1.5W at a 40°C temperature rise. The attachment method uses bolt-on and PC pin mounting, providing mechanical stability.
This heat sink is ideal for thermal management of TO-220 transistors, voltage regulators, and other semiconductor devices in vertical mounting orientation. Its compact size allows for use in dense PCB layouts.
