1.

This data must be considered in adequate power dissipation conditions, the junction temperature must be maintained

below 125 °C.

2.

The exposed pad should be soldered directly to the PCB to get the thermal benefits. The exposed pad can be attached to

a metal land electrically isolated or connected to ground.
