CeraDiode SMD type, case size 0603 Data sheet CDS3 Series B72500D*** 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,...)
