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.
