2 A higher Tj is allowed as an overload condition but at the threshold Tj(TO) the over temperature trip operates to protect the switch.

3 All control logic and protection functions are disabled during conduction of the source drain diode. If the protection circuit was previously

latched, it would be reset by this condition.
