Data Sheet

July 1999

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-

lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess

of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended

periods can adversely affect device reliability.

Fusing Considerations

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone

operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus-

ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The

safety agencies require a normal-blow fuse with a maximum rating of 20 A (see Safety Considerations section).

Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same

type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information.
