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.
Features
ESD protection according to IEC 61000-4-2 (Level 4)
Endurance specification up to 3000 ESD pulses (IEC 61000-4-2 Level 4)
Suitable for uni- and bidirectional lines
Bidirectional ESD protection in a two-pin device
Routes all ESD events, both positive and negative, safely to ground
Suitable for DC working voltages up to 22 V
No derating of maximum ratings up to 85 °C
Surface mount package in 0603 case size
Extremely fast response time < 0.5 ns
Lead free nickel barrier terminations
Application
Desktop and notebook computers
Peripherals
Portable handheld products (e.g. PDA)
Mobile communication
Consumer products (set top box, MP3 player, digital cameras,...)
Liquid crystal displays (LCD) / monitors
