TVS Diode Arrays (SPA ? Diodes)
General Purpose ESD Protection - SP724 Series
SP724 Series 3pF 8kV Diode Array
RoHS
Pb GREEN
Description
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 specification for both
contact and air discharge methods to level 4.

associated power supply lines. Clamping action occurs
during the transient pulse, turning on the diode and fast
triggering SCR structures when the voltage on the input
line exceeds one V BE threshold above the V+ supply (or one
V BE threshold below the V- supply). Therefore, the SP724P
operation is unaffected by poor power supply regulation or
voltage fluctuations within its operating range.
