The Wakefield-Vette 680-5A is a board level heat sink from the 680 Series, designed for efficient thermal management of TO-3 power semiconductors. Its square pin fin geometry maximizes surface area for convection cooling, while the compact 45.97mm x 45.97mm footprint and 12.7mm height allow placement in tight board-to-board spacing applications.
Constructed from black anodized aluminum, the 680-5A offers corrosion resistance and enhanced emissivity. The bolt-on attachment method ensures secure mounting to the TO-3 package. Under forced air convection at 400 LFM, the typical thermal resistance is 3.0°C/W, and it can dissipate 7.5W at a 70°C temperature rise.
This heat sink is suitable for natural convection as well, though specific natural convection performance data is not provided in the available specifications. The omnidirectional pin fin design allows free air circulation regardless of mounting attitude, making it versatile for various PCB layouts.
The 680-5A is designed to cool a TO-3 semiconductor package.
The heat sink is 45.97mm (1.810") square and 12.7mm (0.500") tall.
The typical thermal resistance is 3.0°C/W at 400 LFM forced air.
It can dissipate 7.5W typically at a 70°C temperature rise.
It is made of aluminum with a black anodized finish.
It uses a bolt-on attachment method.
The part is listed as RoHS3 Compliant, but this is unverified low-confidence data.
