Cautions data case with Exposed Die-Pad substrate mounted shows values when more Exposed Die-Pad wet. design, employ derating design with sufficient margin. Stresses derated include voltage, current, junction temperature, power loss, mechanical stresses such vibration, impact, tension. Accordingly, design must ensure these stresses small possible. guideline ordinary derating shown below (1)Maximum value less voltage rating (2)Maximum value less current rating (3)Maximum value less temperature rating After design, sure verify design with actual product. Confirm solder joint state verify also reliability solder joint Exposed Die-Pad, etc. void deterioration, observed solder joint these parts, causes deteriorated thermal conduction, possibly resulting thermal destruction
