7.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted)(1)(2)
MIN MAX UNIT(2)
VIN Input voltage –0.3 6 V
VOUT Output voltage –0.3 6 V
VBIAS Bias voltage –0.3 6 V
VON ON voltage –0.3 6 V
IMAX Maximum continuous switch current 4 A
IPLS Maximum pulsed switch current, pulse <300 µs, 2% duty cycle 6 A
TA Operating free-air temperature(3) –40 85 °C
TJ Maximum junction temperature 125 °C
TLEAD Maximum lead temperature (10-s soldering time) 300 °C
TSTG Storage temperature –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.
(2) All voltage values are with respect to network ground terminal.
(3) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature [TA(max)] is dependent on the maximum operating junction temperature [TJ(max)], the maximum power dissipation of the device in the application [PD(max)], and the junction-to-ambient thermal resistance of the part/package in the application (θJA), as given by the following equation: TA(max) = TJ(max) – (θJA × PD(max)).

7.2 ESD Ratings

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.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
