Short PDF datasheet, 42.1 KB, for the 1N6098 diode, indexed in the schematic section though it covers one discrete component. Nothing beyond the part number appears in the name, so maker and revision are unknown. A sheet like this lists voltage and current ratings, thermal data and the mechanical outline. Technicians consult it when sourcing a replacement or judging whether a substitute will cope with the circuit. Read it in any PDF viewer and match the part marking before relying on its figures.
