Document Type and Number:
WIPO Patent Application WO/2011/104922
Kind Code:
A1
Abstract:
Provided is a surge absorbing circuit which absorbs surges stably and does not affect signals in a signal wire even in the case of high-frequency signals, and also provided is an electronic device which uses the surge absorbing circuit. At least one surge suppressing circuit is provided for the same signal wire (1); the surge suppressing circuit includes at least power supplies (5, 8), diodes (4, 7) which are connected between the signal wire and the power supplies, and power supply wires (111, 112 (10, 11)) which connect the diodes and the power supplies. The directions of the diodes and the voltages of the power supplies for the signal wire are set in such a way that the diodes become reverse biased in each surge suppressing circuit.
