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.

Eco-Status information: Additional details including specific material content can be accessed at www.ti.com/leadfree

GREEN: Ti defines Green to mean Lead (Pb)-Free and in addition, uses less package materials that do not contain halogens, including

bromine (Br), or antimony (Sb) above 0.1% of total product weight.

N/A: Not yet available Lead (Pb)-Free; for estimated conversion dates, go to www.ti.com/leadfree.

Pb-FREE: Ti defines Lead (Pb)-Free to mean RoHS compatible, including a lead concentration that does not exceed 0.1% of total

product weight, and, if designed to be soldered, suitable for use in specified lead-free soldering processes.

Over operating free-air temperature range; all voltages are with respect to GND (unless otherwise noted).

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Dissipation ratings are calculated based on the usage of nine standard thermal vias and thermal pad soldered on the PCB. If thermal

pad is not soldered to the PCB, the junction-to-ambient thermal resistance is 88.6°C/W.
