Note 1: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Under

“

recommended operating conditions” the device operation is assured, but some particular parameter may not be achieved.

The electrical characteristics table defines the operation range of the device, the electrical characteristics is assured on DC and

AC voltage by test program. For the parameters without minimum and maximum value in the EC table, the typical value defines

the operation range, the accuracy is not guaranteed by spec.

Note 2: The maximum power dissipation decrease if temperature rise, it is decided by TJMAX, θ JA, and environment

temperature (TA). The maximum power dissipation is the lower one between PDMAX = (TJMAX - TA)/ θJA and the number

listed in the maximum table.
