Maximum ratings are those values beyond which device damage can occur.Maximum ratings applied to the device are individual stress limit values (notnormal operating conditions) and are not valid simultaneously. If these limitsare exceeded, device functional operation is not implied, damage may occurand reliability may be affected.1.FR−5 = 3.5 X 1.5 inches.
2.Thermal Resistance measurement obtained via infrared Scan Method.
