Document Type and Number:
Japanese Patent JP2011060762
Kind Code:
A
Abstract:
To provide a protective device for preventing effectively overcurrent and overvoltage.
The protective device includes a substrate, a conductive part, and a first auxiliary medium. The conductive part is supported by a substrate and the conductive part is provided with a metal element electrically connected between first and second electrodes. The metal element functions as a sacrifice structure having a melting point lower than the melting point of the first and second electrodes. The auxiliary medium is arranged between the metal element and the substrate, and the auxiliary medium has a melting point lower than the melting point of the metal element. The auxiliary medium promotes fracture upon melting of the metal element.
