PDF datasheet for the 1N4001G rectifier, 171 KB, indexed under the schematic category. The G suffix is used by some vendors for glass-passivated parts, although the name alone does not confirm the maker. The 1N4001 is rated 50 V reverse voltage and 1 A average current. Consult the sheet for surge rating, forward drop, thermal data and cathode marking when replacing an axial rectifier, and compare it with other 1N400x documents in the index to choose the right voltage grade.
