Abstract
A composition for providing protection against electrical overstress (EOS) comprising an insulating binder, doped semiconductive particles, and semiconductive particles. The composite materials exhibit a high electrical resistance to normal operating voltage values, but in response to an EOS transient switch to a low electrical resistance and clamp the EOS transient voltage to a low level for the duration of the EOS transient.
