Next Previous Silicon Protection Circuits TVS Rail Clamp Array in a Surface Mount Package SP0502AAH, SP0506AAA, SP0506AAB, SP0518AAA NEW This family of rail clamp or “diode steering” arrays is designed for very low capacitance ESD protection and is offered in small surface mount packages. 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 5 VDC. 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 low capacitance and clamp voltage are ideal for high speed signal line protection.
