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 1.0 A maximum I
C
value is based upon JEDEC current gain requirements.
The 3.0 A maximum value is based upon actual current handling capability of
the device (see Figures 5 and 6).
