Prior to the onset of overvoltage clamping. For voltages above this value, safe operation is limited by the overvoltage clamping energy.
2
A higher T
j
is allowed as an overload condition but at the threshold T
j(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.
