6.1 Absolute Maximum Ratings

Unless otherwise noted: voltages are respect to SOURCE connected to reference ground(1)
MIN MAX UNIT
VDS Drain-source voltage, FET Off 650 V
VDS(surge) Drain-source voltage, FET Switching, surge condition(2) 720 V
VDS,tr Drain-source transient ringing peak voltage, FET Off, surge condition(3) 800 V
Pin voltage VDD -0.3 20 V
LDO5V -0.3 5.5 V
VNEG -16 0.5 V
BBSW VVNEG–1 VVDD+0.5 V
IN -0.3 20 V
/FAULT, /OC, TEMP -0.3 VLDO5V+0.3 V
RDRV -0.3 5.5 V
ID(RMS) Drain RMS current, FET on 44 A
ID(pulse) Drain pulsed current, FET on, tp < 10 µs(4) -96 Internally Limited A
IS(pulse) Source pulsed current, FET off, tp < 1 µs 60 A
TJ Operating junction temperature(5) -40 150 °C
TSTG Storage temperature -55 150 °C
(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) See Section 8.3.3 for an explanation of the switching cycle drain-source voltage ratings.
(3) t1 < 200 ns in Figure 8-1.
(4) The positive pulsed current must remain below the overcurrent threshold to avoid the FET being automatically shut off. The FET drain intrinsic positive pulsed current rating for tp < 10 µs is 96 A.
(5) Refer to the Electrical and Switching Characteristics Tables for junction temperature test conditions.
