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. These ratings are based on a maximum junction temperature of 200_C.
2. These are steady−state limits. onsemi should be consulted on applications
involving pulsed or low−duty−cycle operations.
