1 Prior to the onset of overvoltage clamping. For voltages above this value, safe operation is limited by the overvoltage clamping energy.
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.
