CeraDiode
Reliable ESD protection of single lines
Description
Due to the ongoing miniaturization, today's electronic devices are more and more sensitive to
electrostatic discharges (ESD) and overvoltages. Therefore reliable protection components become
absolutely necessary to harden your valuable electronics against the impact of ESD.
CeraDiodes are ceramic semiconductors optimized specifically for high performance in Electro Static
Discharge (ESD) applications. The device has a non-linear voltage/current characteristic that is highly
optimized for effectively suppressing extremely fast voltage transients. The device offers superior
parametric stability over the complete operating range of 40 C to +85 C.
CeraDiodes are bi-directional devices. A single CeraDiode
connected from signal/dataline to ground
routes both positive and negative ESD transitions safely to the ground plane. This technique
eliminates the need to route ESD charge into the power plane, possibility damaging nearby integrated
circuits.
