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, i

The maximum power dissipation is the lower one between

Power MOSFET.
