Jul 30, 2011 · I was learning about the datasheets and part numbers of electronic components. An an example you can have a look on the datasheet of 1N4001-1N4007 (part numbers) diode here. 1: Is this possible that the datasheet of one manufacturer for, say, 1N4001 could differ from the other? 2: Do the diode families differ by their ampere rating?
