7.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VIN Input voltage range –0.3 6 V
VBIAS Bias voltage range –0.3 6 V
VOUT Output voltage range –0.3 6 V
VON ON pin voltage range –0.3 6 V
IMAX Maximum Continuous Switch Current, TA = 25°C 15 A

TJ Maximum junction temperature 125 °C
TSTG Storage temperature range –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.
