Named simply 85eps, this 79.2 KB PDF is catalogued as a schematic, without any manufacturer or board details. It likely covers a rectifier series rather than one specific voltage grade, but read the document to be sure. Material of this type usually tabulates several voltage classes along with current ratings, forward drop and package drawings. Use it to identify which grade a part on the board belongs to and to compare ratings when sourcing a replacement, checking the full suffix printed on the component.
