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 surge voltage (FET Switching)(2) 720 V
VDS,tr Drain-source transient ringing peak voltage (FET Off)(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
VIN -0.3 20 V
/FAULT, /OC, /TEMP -0.3 V5V+0.5 V
RDRV -0.3 5.5 V
ID(RMS) Drain RMS current (FET On)(4) 55 A
ID(pulse) Drain pulsed current (FET On, tp < 10 µs) -125 Internally Limited A
IS(pulse) Source pulsed current (FET Off, tp < 10 µs) 80 A
TSTG Storage temperature -55 150 °C
TJ Operating Junction Temperature -40 150 °C
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.
Voltage while operating under surge conditions for 50 strikes (per VDE 0884-11) of the IEC61000-4-5 surge waveform applied to a half-bridge hard-switching at 100 kHz.
Transient ringing peak voltage after device turn-off while operating under surge conditions in (2) above. Peak voltage damped to ≤ 720 V within 1 µs.
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 125 A.
