General Purpose ESD Protection - SP723 Series
Peak Transient Current Capability of the SP723
The peak transient current capability rises sharply as the
width of the current pulse narrows. Destructive testing
was done to fully evaluate the SP723’s ability to withstand
a wide range of peak current pulses vs time. The circuit
Figure 4: Typical SP723 Peak Current Test Circuit
with a Variable Pulse Width Input
used to generate current pulses is shown in Figure 4.
The test circuit of Figure 4 is shown with a positive pulse
input. For a negative pulse input, the (-) current pulse input
goes to an SP723 ‘IN’ input pin and the (+) current pulse
input goes to the SP723 V- pin. The V+ to V- supply of the

SP723 must be allowed to float. (i.e., It is not tied to the
ground reference of the current pulse generator.) Figure
5 shows the point of overstress as defined by increased
leakage in excess of the data sheet published limits.

The maximum peak input current capability is dependent
on the ambient temperature, improving as the temperature
is reduced. Peak current curves are shown for ambient
temperatures of 25oC and 105oC and a 15V power supply
condition. 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

CAUTION: SAFE OPERATING CONDITIONS LIMIT
Note that adjacent input pins of the SP723 may be
paralleled to improve current (and ESD) capability. The
sustained peak current capability is increased to nearly
twice that of a single pin.
