A 50.0 KB PDF with the code 30SCLJQ060, catalogued as a schematic but clearly following a semiconductor part-number format. Likely a datasheet for a rectifier closely related to the 30SLJQ series, with the extra letter possibly marking a package or configuration variant. Technicians use it to check pin arrangement, especially where a package holds two diodes, and to read voltage and current limits. Confirm the marking on the physical part matches exactly, because the SCLJQ and SLJQ versions may differ in internal configuration.
