This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTE: 1. θJA is measured with the component mounted on an evaluation PC board in free air.

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.
