173-7-240A Description

Short technical summary and product information.

The Wakefield-Vette 173-7-240A is a rectangular thermal pad designed for use with TO-220 packages. It measures 19.10mm by 12.70mm with a thickness of 0.178mm (0.0070 inches). The pad features a polyimide backing with adhesive on one side for secure attachment to the component or heatsink.

 

Thermal performance is specified with a thermal conductivity of 1.2W/m-K and a thermal resistivity of 0.33°C/W, providing effective heat transfer from the semiconductor to the cooling solution. The gray color is typical of polyimide-based thermal interface materials.

 

This pad is suitable for applications requiring electrical isolation and thermal management in a compact form factor. The adhesive layer simplifies assembly by eliminating the need for additional thermal grease or mounting hardware.
