Applications

PPD ML PM 08/12

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 61000-4-2

All TDK-EPC Chip Varistors fulfill at least IEC 61000-4-2, level 4 (8 kV contact discharge, 15 kV air discharge). The response time of MLV is <0,5 ns.
