Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. The heat generated must be less than the thermal conductivity from
Junction-to-Ambient: dP_D/dT_J < 1/R_qJA.
