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 in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Notes
a. Surface Mounted on 1” x 1” FR4 Board.
b. Junction-to-foot thermal impedance represents the effective thermal impedance of all heat carrying leads in parallel and is intended for use in conjunction with
the thermal impedance of the PC board pads to ambient (R_thJA = R_thJF + R_thPCB-A). It can also be used to estimate chip temperature if power dissipation and
the lead temperature of a heat carrying (drain) lead is known.
