    • PROBLEM TO BE SOLVED: To prevent an excessive current from flowing through a protection device, and also to prevent latch-up. SOLUTION: A surge protection circuit includes a surge detection circuit 14 for detecting a surge applied to a semiconductor integrated circuit, and the protection device 15 for absorbing the surge. The protection device is arranged between a signal terminal for inputting a signal to the semiconductor integrated circuit and a power source terminal for supplying a power source voltage. When the surge detection circuit does not detect any surge while the power source voltage is not larger than a voltage enough to normally operate the semiconductor integrated circuit, the protection device is set in a current limiting state, and when the surge detection circuit detects a surge while the power source voltage is not larger than a voltage enough to normally operate the semiconductor integrated circuit, the protection device is set in a current non-limiting state.
