SP0518CAA

Next Previous Silicon Protection Circuits TVS Rail Clamp Diode Array with an Avalanche Diode SP0506CA, SP0518CAA NEW This family of rail clamp or “diode steering” arrays are designed for very low capacitance ESD protection and is offered in small surface mount packages. An Avalanche diode has been added between VP and VN to suppress transients on the supply rails. The multi-channel devices are used to help protect high speed sensitive digital or analog input circuits on data, signal, or control lines with unipolar voltage levels up to 5VDC. The state-of-the-art structure is designed to suppress ESD and other transient over-voltage events to meet the International Electrotechnical Compatibility (IEC) transient immunity standards IEC 61000-4-2 for Electrostatic Discharge Requirements. The monolithic silicon devices are comprised of specially designed low capacitance structures for transient voltage suppression (TVS). The size and shape of these structures have be tailored for transient protection. The very low capacitance and clamp voltage are ideal for ultra high speed signal line protection.
