CeraDiode
Reliable ESD protection of high speed signal 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. The CDS2C16GTH exhibits a very low capacitance, making it the ideal solution for direct
connection to high speed signal lines. The result is maximum protection with minimal signal distortion.

As far as possible, the components shall be employed within 12 months. They should be left in their
original packings to avoid soldering problems due to oxidized contacts. Storage temperature: 25 to
45 C. Relative humidity: <75 % annual average, <95 % on max. 30 days in a year.
The usage of mild, non activated fluxes for soldering is recommended, as well as proper cleaning of
the PCB.
