The EA-T220-38E from Ohmite is a board level vertical heatsink designed for the TO-220 semiconductor package. It features a rectangular fin shape with black anodized aluminum construction. The heatsink measures 38.10mm (1.500") in length, 35.00mm (1.378") in width, and a fin height of 12.70mm (0.500").
Attachment is achieved via bolt on and PC pin methods, providing secure mounting to the PCB. Under natural convection, the thermal resistance is 10.40°C/W. With forced air flow at 300 LFM, the thermal resistance drops to 4.00°C/W. The maximum power dissipation is 8.0W at a temperature rise of 80°C.
This heatsink is suitable for applications requiring efficient thermal management of TO-220 devices such as linear regulators, power transistors, and MOSFETs. The black anodized coating enhances heat radiation and provides corrosion resistance.
