[Amps] DIODE PIV Confusion

[Steve Katz]

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.
