Abstract
A nonlinear resistive surface mount device for protecting against electrical overvoltage transients is disclosed which includes a pair of conductive sheets and a foldback switching material disposed between the pair of conductive sheets. This configuration serves to connect the conductive sheets by a foldback switching mechanism thereby providing predetermined resistance when the voltage between the conductive sheets exceeds a predetermined voltage.
