2/3 of the manufacturers have 6A01 to 6A10 for 100 to 1000 volt PIV
1/3 list 6A05 to 6A100 for 50 to 1000V PIV.
There are clearly different manufacturers with different numbering schemes.
Surge and Taiwan Semiconductors use the 6A05 to 6A100 scheme and so do others.

I read that but that's just a matter of manufacturers making up rules as they
go along.
IRC registered the 6A series with JEDEC over 30 years ago, and the registration
says a 6A10 is 1kV. A 6A01 is 100V, and they're all the same size; the only
difference is the die inside. The 100V parts are fallouts that were intended
to diffuse to higher breakdown voltages and missed. But the die size is the
same, as is the package size, for all of them.

Dick, the reason for the confusion is that there are indeed 2 different
diodes with that designation! Mouser, for example, lists both of them.
Take a look at both data sheets, and check the physical dimensions. The 1
KV 6A10 is huge, with a diameter (IIRC) of about 1/3". If the diode is
substantially smaller, it's the 100volt diode. If you order 6A10's from a
reputable dealer, you can easily verify that the part they're selling is
indeed a 1 KV 6A device.

In looking for a datasheet for the 6A10 diode I came across a
potentially hazardous find.
One datasheet said the 6A10 was a 100 volt PIV diode, while another
said it was a 1,000
volt PIV diode.
So, unless I actually measure the PIV, I am not sure of what I have
and must, for safety sake,
assume the worst.
