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.

The SP723 has a Level 4 HBM capability when tested as a device to the

IEC 61000-4-2 standard. Level 4 specifies a required capability greater

than 8kV for direct discharge and greater than 15kV for air discharge.

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 SP723 ESD capability is typically greater than 25kV from

100pF through 1.5kΩ. By strict definition of MIL-STD-3015.7 using “pin-

to-pin” device testing, the ESD voltage capability is greater than 10kV.

For the SP723 EIAJ IC121 Machine Model (MM) standard, the ESD capa-

bility is typically greater than 2kV from 200pF with no series resistance.
