Slide 6: Electrostatic discharge (ESD) events
Attracting Tomorrow Electrostatic discharge (ESD) events Electrostatic discharge (ESD) is a fast and high voltage transient. 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 require

Slide 9: Application example: LED
Attracting Tomorrow Application example: LED LEDs are very ESD sensitive with a typical protection level of 100 to 500 V. EPCOS offers protection solutions for level 2 (L2) where the CeraDiode® is on the LED flash module and/ or the light engine. Example Protection concept: 1 CeraDiode® per LED stri
Slide 10: Application example: Bar code scanner
Attracting Tomorrow Application example: Bar code scanner ESD can occur when touching a bar code scanner. The unwanted pulse may damage the components inside and thus its function. Multilayer ESD protection devices are used to protect ESD sensitive components preventing damage to the board. Recommen
Slide 11: Protection against high energy transients
Attracting Tomorrow Protection against high energy transients Industrial applications and automation equipment require protection against various transients, such as ESD, Electrical Fast Transients (EFT) or burst, but also against high energy transients, so called surges. Surges are caused by switch
Slide 12: Surge current protection
Attracting Tomorrow Surge current protection Pulse energy Waveform ● Very high current flows caused by surge voltages or spikes, like lightning coupled over network are referred as surge currents. Such surge currents deposit much more energy than ESD pulses and thus requires much higher energy absor
