SP0506CA, SP0518CAA
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.
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.
