26176CTE Description

Short technical summary and product information.

The 26176CTE is a board level heat sink from Wakefield-Vette designed for cooling TO-263 (D²Pak) surface mount packages. It features a rectangular shape with fins to enhance heat dissipation. The heat sink is constructed from copper with a tin finish, providing good thermal conductivity and corrosion resistance. It uses a clip attachment method for secure mounting to the package.

Key specifications include a width of 25.40mm (1.000"), a length of 19.38mm (0.763"), and a fin height of 11.43mm (0.450"). The thermal resistance is rated at 11.00°C/W under natural convection conditions. This heat sink is suitable for applications requiring passive cooling of TO-263 devices in natural convection environments.

The part is RoHS3 compliant and has an MSL of 1 (unlimited). It is commonly used in power management, motor control, and other circuits where efficient thermal management of surface mount packages is needed.
