Abstract
The utility model discloses a diode with a heat radiation bottom surface. The diode with the heat radiation bottom surface includes electrodes and a shell. The shell is with a downward opening structure, and the opening end is fixedly connected with a bottom board which has an area the same with the area of the opening of the shell. The electrodes penetrate the bottom board and are connected with the bottom board in a fixed manner. In the diode with the heat radiation bottom surface, the opening end of the shell is fixedly connected with the metal bottom board whose area is the same with the area of the opening of the shell, and therefore heat radiation performance is greatly improved and service life is extended.
