TVS Diode Arrays
Surface Mount TVS Avalanche Diode Array
SP0502BA, SP0503BA, SP0504BA, SP0505BA, SP0506BA
The surface mount family of arrays are designed to suppress ESD and
other transient overvoltage events. These arrays are used to meet the
International Electrotechnical Compatibility (IEC transient immunity standards IEC 61000-4-2 for Electrostatic Discharge Requirements). The
series are used to help protect sensitive digital or analog input circuits
on data, signal, or control lines with voltage levels up to 5VDC.
The monolithic silicon arrays are comprised of specially designed
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.
