Applications notes like this have been indispensable in designing the T400 temperature datalogger, for which we used TVS diodes and a thermal fuse.

USB data-acquisition modules offer good value and ease of use, which makes them an attractive choice for manufacturing test. But before you use the modules in a manufacturing test system, you need to take steps to protect them. During manufacturing test of circuit boards or subassemblies, a defect in an assembly may result in a condition that damages a data-acquisition module.
