Believe it or not, searching for a 2A 100V diode brought up a couple dozen 1N4148 with current ratings from 100mA to 2A. They can't all be right, otherwise the part number is meaningless.
1n4148 might take 2 A, once. After that, zero. They are glass; look at the size of the bond wire in there.
I get my datasheets from datasheetcatalog.com newark digikey or mouser (link to manufacturer). Fewer lies. Alldata can't even get the type of semiconductor right.
If you're looking at the speaker back voltage protector diodes, experience has proved 1n4003 is not enough. Manufacturers spent the extra $.02 for 3 A parts, for a reason: warrenty returns. Same for the rail supply rectifier. 1n4003 is good enough for 20 w/ch @8 ohms amps.
