RELIABLE ESD PROTECTION OF HIGH SPEED DATA LINES
Description
Today’s electronic devices are more and more sensitive to electrostatic discharges (ESD) and
overvoltages. Therefore reliable protection components become absolutely necessary.
Cera Diodes are ceramic semiconductors with a nonlinear voltage-current characteristic comparable
to Zener- and TVS-Diodes, for hardening your valuable electronic against the impact of ESD. They
offer a fast response time and a stable behaviour at ambient temperatures up to 85°C. Thanks to their
low capacitance High Speed Cera Diodes offer very low signal distortion for high speed data
transmission applications.

The components should be soldered within 12 months after delivery from EPCOS. The parts
are to be left in the original packing in order to avoid any soldering problems caused by
oxidized terminals.
Storage temperature: -25 to 45°C
Relative humidity: <75% annual average, <95% on max. 30 days in a year.
The use of mild, non activated fluxes for soldering is recommended, as well as proper
cleaning of the PCB.
