Abstract

A quad flat pack (QFP) integrated circuit package that is modified to include a tab that increases the thermal efficiency of the package. The package contains an integrated circuit that is mounted to a die paddle of a lead frame. A plurality of leads extend from a first side of the die paddle. Placing all of the leads on one side of the package minimizes the difference in signal length between the leads. The tab extends from a second side of the die paddle. Both the leads and the tab extend from a plastic housing which encapsulates the integrated circuit. The tab provides a large conductive area which increases the heat transfer rate from the integrated circuit to the ambient, or an external thermal element.
