Abstract
An over-current protection device, which can be surface-mounted and stand upright on a circuit board and withstand 60 to 600 volts, comprises a PTC device, first and second electrodes. The PTC device is a laminated structure comprising first and second conductive layers and a PTC material layer. The first and second conductive layers are in physical contact with first and second planar surfaces of the PTC material layer, respectively. The first electrode is disposed on the first conductive layer. The second electrode is disposed on the second conductive layer and is separated from the first electrode. The first electrode, the second electrode and the PTC device commonly form an end surface which is substantially perpendicular to the first and second planar surfaces. The first electrode and the second electrode at the end surface serve as interfaces electrically connecting to the circuit board.
