Applications

TheSP724isaquadarrayoftransientvoltageclamping

circuitsdesignedtosuppressESDandothertransientover-

voltageevents.TheSP724isusedtohelpprotectsensitive

digitaloranaloginputcircuitsondata,signal,orcontrol

linesoperatingonpowersuppliesupto20VDC.

TheSP724iscomprisedofbipolarSCR/diodestructures

toprotectuptofourindependentlinesbyclamping

transientsofeitherpolaritytothepowersupplyrails.The

SP724offersverylowleakage(1nATypical)andlowinput

capacitance(3pFTypical).Additionally,theSP724israted

towithstandtheIEC61000-4-2ESDspecicationforboth

contactandairdischargemethodstolevel4.

TheSP724isconnectedtothesensitiveinputlineandits

associatedpowersupplylines.Clampingactionoccurs

NOTES:

1. The design of the SP724 SCR/Diode ESD Protection Arrays are

covered by Littelfuse patent 4567500.

2. The full ESD capability of the SP724 is achieved when wired in a

circuit that includes connection to both the V+ and V- pins. When

handling individual devices, follow proper procedures for

electrostatic discharge.
