ESTW025A0F Series Eighth-Brick Power Modules
36–75Vdc Input; 3.3Vdc Output; 25A Output
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
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 the device reliability.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an
integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included,
however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies
require a fast-acting fuse with a maximum rating of 5 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 sheet for further information.
