Open-mode protection device and electronic device having same

An open-mode protection device connected in parallel to a constant current source and a load configured with a light emitting diode (LED), the open-mode protection device comprising:

• a protection unit having electrodes provided at first and second sides of the protection unit connected to electrodes of a pair of current suppressing units such that the series connection of the pair of the current suppressing units and the protection unit together are connected in parallel with the load, wherein the protection unit is configured to bypass an overvoltage or an overcurrent, wherein the pair of the current suppressing units are configured with a pair of substrates wherein the pair of the current suppressing units are spaced apart from each other by a predetermined distance, and wherein the pair of the current suppressing units are disposed on the same plane;
• and
• a molding unit formed to cover at least one side of each current suppressing unit of the pair of the current suppressing units and at least one side of the protection unit,
• wherein the pair of current suppressing units is electrically disposed in series on a current path through the protection unit at the first and second sides of the protection unit and configured to sense a temperature of the protection unit and to reduce a current of the protection unit as a temperature of the protection unit increases by increasing a voltage of the protection unit while the constant current source supplies a constant current and when a load configured with the light emitting diode (LED) enters an open state.
