General Purpose ESD Protection - SP724 Series
Peak Transient Current Capability for Long Duration Surges
The peak transient current capability is inversely
proportional to the width of the current pulse. Testing was
done to fully evaluate the SP724’s ability to withstand long

duration current pulses using the circuit of Figure 4. Figure
5 shows the point of overstress as defined by increased
leakage in excess of the data sheet published limits.
The safe operating range of the transient peak current
should be limited to no more than 75% of the measured
overstress level for any given pulse width as shown in the
curve of Figure 5.
The test circuit of Figure 4 is shown with a positive pulse

goes to an SP724 ‘IN’ input pin and the (+) current pulse
input goes to the SP724 V- pin. The V+ to V- supply of the

SP724 must be allowed to float. (i.e., It is not tied to the

ground reference of the current pulse generator.)
Note that two input pins of the SP724 may be paralleled to
improve current (and ESD) capability. The sustained peak
current capability is increased to nearly twice that of a
single pin.
