The SP724AHTG is a TVS Diode Array with matte tin-plated copper alloy leads and moulded epoxy body. The SP724 is a quad array of transient voltage clamping circuits designed to suppress ESD and other transient overvoltage events. The SP724 is used to help protect sensitive digital or analogue 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 specification for both contact and air discharge methods to level 4.
