| Zusammenfassung: | The utility model discloses a triode with a heat radiation surface. The triode with the heat radiation surface comprises a semiconductor chip (10), an insulation heat conduction layer (20) and a base plate (30). The semiconductor chip is provided with three pins (100). The three pins are respectively connected to a current collecting zone, a base zone and an emission zone of the semiconductor chip. The insulation heat conduction layer is fixed on the bottom surface of the semiconductor chip. The bottom surface of the insulation heat conduction layer is fixed on the base plate. The base plate is provided with a protruding portion (300). The protruding portion is provided with a fixing hole (301). The top surface of the protruding portion is wavy. According to the above technical scheme, the wavy top surface of the protruding portion of the base plate is a main heat radiation surface of the triode of the utility mode. Through the technical scheme of the utility model, even if the size of the triode is continuously reduced, the actual heat radiation area of the triode will not decrease, so that heat radiation effects of the triode will not be influenced and the stability of the function of the triode can be guaranteed. |
