5.2 UL 1577

UL 1577 is Underwriters Laboratories safety standard for optical isolators but it is also used to certify other semiconductor components such as digital isolators. This standard recognizes components as either single protection or double protection based on several environmental and dielectric withstand voltage tests. This standard does not have any minimum DTI criteria for certification and ratings are accorded to the components based on the dielectric strength of the insulation material.
