Provided is a device including a series circuit in which a rectifying element and a fuse element are connected in series, in which one end on an anode side of the rectifying element in the series circuit is connected to a first connection point having a reference potential, and another end on a cathode side of the rectifying element in the series circuit is connected to a second connection point that is to have a potential higher than the reference potential. The device may further include a parallel circuit in which a plurality of the series circuits is connected in parallel. A rectifying characteristic of the rectifying element in at least one of the series circuits connected in parallel may be different from a rectifying characteristic of the rectifying element in at least another one of the series circuits connected in parallel.
