These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Lead Temperature (Soldering, 10 seconds) 300°C
(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when
operating the device outside the rated Operating Conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) Unless otherwise stated, load currents are pulses with widths less than 2 ms and duty cycles less than 5%.
(4) The maximum allowable power dissipation at any ambient temperature is P
Max
= (125 − T
A
)/θ
JA
, where 125°C is the maximum junction
temperature for operation, T
A
is the ambient temperature in °C, and θ
JA
is the junction-to-ambient thermal resistance in °C/W. Exceeding
P
max
voids the Electrical Specifications by forcing T
J
above 125°C. If the junction temperature exceeds 155°C, internal circuitry disables
the power bridge. When a heatsink is used, θ
JA
is the sum of the junction-to-case thermal resistance of the package, θ
JC
, and the case-
to-ambient thermal resistance of the heatsink.
(5) ESD rating is based on the human body model of 100 pF discharged through a 1.5 kΩ resistor. M1, M2, M3 and M4, pins 8, 7, 6 and 4
are protected to 800V.
