TITLE: OVERVOLTAGE PROTECTION ABSTRACT The overload protection material of this invention comprises a plastic preferably an elastomer, e.g. silicone rubber, homogeneously and highly loaded with silicon carbide particles (powder) and a lesser amount of a Group IV B element-carbide particles (powder). The material is preferably form stable and is placed (across) a semiconductor junction or between electrodes of a device to be pro- tected so that when high voltage surges appear across the junction or device to be protected the material breaks down (conducts) before the junction or device is destroyed. The material is bidirectionally conductive in its voltage threshold characteristic and repeatedly recovers unlike a fuse so that it provides continuous high voltage over-voltage (e.g. surge) protection.
