Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are xceeded, device functional operation is not implied, damage may occur and reliability may be affected.
1. 10 X 1000 s, non−repetitive
2. 1, square copper pad, FR−4 board
