Abstract

A self-securing heat sink for transistors and the like comprises a unitary member that is constructed from a malleable material having a high heat transfer coefficient. The unitary member includes a base portion, at least one heat radiating fin portion, and a clip portion that is capable of engaging a transistor to retain the heat sink securely on the transistor without necessitating the use of threaded fasteners, rivets, or the like.
