Refers to common-mode transients across the insulation barrier. Common-
mode transients exceeding the absolute maximum ratings may cause latch-
up or permanent damage.

Analog Devices recommends that reflow profiles used in soldering RoHS
compliant devices conform to J-STD-020D.1 from JEDEC. Refer to JEDEC for
the latest revision of this standard.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
THERMAL RESISTANCE
θJA and θJC are specified for the worst-case conditions, that is, a
device soldered in a circuit board for surface-mount packages.

Refers to the continuous voltage magnitude imposed across the isolation barrier. See the Insulation Lifetime section for more details.
Note that greater working voltages than the values presented in Table 8 shorten the lifetime of the product (see the Insulation Lifetime
section). Therefore, although some certifications in Table 2 state bigger maximum working voltages, use the ADE7912/ADE7913 only for
working voltages lower than the values presented in this Table 8.
