1. [Amps] DIODE PIV Confusion (score: 1): Author: Richard Solomon <dickw1ksz@gmail.com>; Date: Wed, 29 Jun 2011 09:28:15 -0700; 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, u; /archives//html/Amps/2011-06/msg00316.html (7,026 bytes)

You could measure the voltage at which it avalanches, but that would not be the PIV. Personally I would look at the circuit; /archives//html/Amps/2011-06/msg00318.html (7,949 bytes)

Can't have a common P/N with different ratings. The 6A01 is the 100V version of a 6A10 (which is 1000V). 73 Steve WB2WIK I remember reading (on amps?; /archives//html/Amps/2011-06/msg00323.html (10,140 bytes)

The manufacturer data sheets, for example from DIODES INC. et al., all show 1000V for a 6A10.

Re: [Amps] DIODE PIV Confusion (score: 1): Author: "Robert Dorchuck" <w6vy@verizon.net>; Date: Wed, 29 Jun 2011 14:33:31 -0700; And if you look at the datsheets from Taiwan Semiconductor the 6A10 is 100 PIV and the 6A100 is 1000PIV. Same as listed in the Mouser catalog. Guess it pays to look close. Bob W6VY __________________; /archives//html/Amps/2011-06/msg00331.html (9,220 bytes)

Re: [Amps] DIODE PIV Confusion (score: 1): Author: K1SG@aol.com; Date: Wed, 29 Jun 2011 19:20:40 EDT; Dick, the reason for the confusion is that there are indeed 2 different diodes with that designation!

IRC registered the 6A series with JEDEC over 30 years ago, and the registration says a 6A10 is 1kV. A 6A01 is 1; /archives//html/Amps/2011-06/msg00333.html (9,695 bytes)

IIRC, both 4CX250B and 4CX1000A want 300 V on the screen, but I'm sure; /archives//html/Amps/2011-06/msg00336.html (9,762 bytes)
