The Ohmite C220-075-3AE is a board level vertical heat sink designed for cooling up to three TO-220 semiconductor packages. It features a rectangular fin shape with a fin height of 0.710 inches (18.03mm) to enhance convective heat transfer. The heat sink is constructed from aluminum with a black anodized finish, which improves corrosion resistance and thermal emissivity.
Dimensions include a length of 75.00mm (2.953 inches) and a width of 38.10mm (1.500 inches). Attachment is achieved using three clips and a PC pin, ensuring secure mounting to the PCB. This vertical orientation allows for efficient airflow in confined spaces, making it suitable for various power management applications.
While thermal resistance and power dissipation ratings are not provided in the available data, the design is optimized for moderate power dissipation in TO-220 devices. The black anodized finish also aids in heat radiation. This heat sink is commonly used in power supplies, motor drives, and other circuits requiring thermal management of multiple TO-220 components.
