1 CERA DIODE RELIABLE ESD PROECION OF HIGH SPEED DAA LINES Description oday s electronic devices are more and more sensitive to electrostatic discharges (ESD) and overvoltages. herefore reliable protection components become absolutely necessary. Cera Diodes are ceramic semiconductors with a nonlinear voltage-current characteristic comparable to Zener- and VS-Diodes, for hardening your valuable electronic against the impact of ESD. hey offer a fast response time and a stable behaviour at ambient temperatures up to 85 C. hanks to their low capacitance High Speed Cera Diodes offer very low signal distortion for high speed data transmission applications. Features ESD protection according to IEC (level 4) Suitable for uni- and bidirectional lines Bidirectional characteristic Working voltage: 16 V Low Capacitance (3pF) No derating up to max. operating temperature Leadless chip with small dimensions Applications Desktop and Notebook computers Portable handheld products (PDA) Mobile communication Consumer products (Set op Box, MP3 Player...) Liquid Crystal Displays (LCD) / Monitors Example: Protection of I/O Lines I/O CDS3C... ESD sensitive device ISSUE DAE ISSUE c PUBLISHER KB VS PE PAGE 1/7
