Embodiments of the present disclosure disclose a circuit protection device comprising a thermal fuse and a diode. The thermal fuse is packaged in a first insulation layer, and the diode is packaged in a second insulation layer. A first exterior electrode pad, a second exterior electrode pad and a third exterior electrode pad are provided on a bottom surface of the first insulation layer. The first electrode surface of the diode and the first electrode end of the thermal fuse are electrically connected to the first exterior electrode pad, the second electrode end of the thermal fuse is electrically connected to the second exterior electrode pad, and the second electrode surface of the diode is electrically connected to the third exterior electrode pad. In this disclosure, the thermal fuse and the diode are integrated into one single circuit protection device, which can be soldered onto the protected circuit in one single process through SMT, thereby it is convenient to use. Further, in the present disclosure, the whole circuit protection device has a very compact structure and a smaller volume. |
