ESD Capability
ESD capability is dependent on the application and defined
test standard. The evaluation results for various test
standards and methods based on Figure 1 are shown in
Table 1.
For the “Modified” MIL-STD-3015.7 condition that is defined
as an “in-circuit” method of ESD testing, the V+ and V- pins
have a return path to ground and the SP720 ESD capability
is typically greater than 15kV from 100pF through 1.5k
strict definition of MIL-STD-3015.7 using “pin-to-pin” device
testing, the ESD voltage capability is greater than 6kV. The
MIL-STD-3015.7 results were determined from AT&T ESD
Test Lab measurements.
. By
The HBM capability to the IEC 1000-4-2 standard is greater
than 15kV for air discharge (Level 4) and greater than 4kV
for direct discharge (Level 2). Dual pin capability (2 adjacent
pins in parallel) is well in excess of 8kV (Level 4).
For ESD testing of the SP720 to EIAJ IC121 Machine Model
(MM) standard, the results are typically better than 1kV from
200pF with no series resistance.

NOTES:
2. In automotive and battery operated systems, the power supply lines should be externally protected for load dump and reverse battery. When the
V+ and V- pins are connected to the same supply voltage source as the device or control line under protection, a current limiting resistor should
be connected in series between the external supply and the SP720 supply pins to limit reverse battery current to within the rated maximum
limits. Bypass capacitors of typically 0.01
μ
F or larger from the V+ and V- pins to ground are recommended.
3. Refer to the Figure 3 graph for definitions of equivalent “SCR ON Threshold” and “SCR ON Resistance.” These characteristics are given here
for thumb-rule information to determine peak current and dissipation under EOS conditions.
