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 maximum package power dissipation limit must not be exceeded.

2. The value of QJA is measured with the device mounted on a 3in x 3in, 4 layer, 0.062 inch FR−4 board with 1.5 oz. copper on the top and

3. 60−180 seconds minimum above 237°C.
