TVS Avalanche Diode in a Chip Scale Package

The product is a silicon P/N structure tailored for ESD protection and is offered in the standard EIA 0402 size. The single channel Chip Scale device is used to help protect sensitive digital or analog input circuits on data, signal, or control lines with voltage levels up to 5VDC. The bipolar device is ideal for protection where AC signals are present. The state-of-the-art device is designed to suppress ESD and other transient over-voltage events to meet the International Electrotechnical Compatability (EMC transient immunity stantards IEC 61000-4-2 for Electrosatic Discharge Requirements). The monolithic silicon device is comprised of specially designed structures for transient voltage suppression (TVS). The size and shape of these structures has been tailored for transient protection. The low capacitance and clamp voltage are ideal for high speed signal line protection.
