Abstract
Printed circuit boards including voltage switchable dielectric materials (VSDM) are disclosed. The VSDMs are used to protect electronic components, arranged on or embedded in printed circuit boards, against electric discharges, such as electrostatic discharges or electric overstresses. During an overvoltage event, a VSDM layer shunts excess currents to ground, thereby preventing electronic components from destruction or damage.
