7 Multilayer Varistors Applications

8 ESD protection Electrostatic discharge (ESD) are fast and high voltage transients. ESD transients are frequently caused by touching a device or contact with the fingers. More than 15 kv can be charged in a human body, thus a protection device for ESD requires high voltage withstand and very short response time. Model of ESD protection Test circuit (HBM) acc. IEC All TDK-EPC Chip Varistors fulfill at least IEC , level 4 (8 kv contact discharge, 15 kv air discharge). The response time of MLV is <0,5 ns.
