Abstract
An ESD protective device is provided which can lower a discharge start voltage. In an ESD protective device 1, first and second discharge electrodes 3 and 4 are disposed in a substrate 2 in a spaced relation with a discharge gap G interposed therebetween, and a conductor 9 is arranged around the discharge gap G. The conductor 9 has a nonlinear sectional shape in a section of the substrate 2 extending in a direction interconnecting a first principal surface 2a and a second principal surface 2b of the substrate 2 and passing the discharge gap G.
Claims7
An ESD protective device comprising:
- a substrate having a first principal surface and a second principal surface, the second principal surface being positioned on a side opposite to the first principal surface;
- first and second discharge electrodes disposed in the substrate and arranged in a spaced relation with a discharge gap interposed therebetween;
- first and second outer electrodes disposed on outer surfaces of the substrate and electrically connected to the first and second discharge electrodes, respectively;
- and
- a conductor arranged around the discharge gap,
- wherein the conductor has a nonlinear sectional shape in a section of the substrate extending in a direction interconnecting the first principal surface and the second principal surface of the substrate and passing the discharge gap.
