Re: Fat Diode help
this sounds like a selenium diode. the square plates are heat sinks, the
round things are washers, the selenium is between the square plates and the
round washers. I'd assume this to be a low voltage - one section can be
maybe 12 to 50 volts, I've seen these up to 250 volts or so but not a lot
higher. They are also far less efficient than silicon rectifiers (much
higher forward voltage drop). They used to be used in battery chargers
because they could survive a short circuit (because the forward voltage drop
was so high). Keep it as a relic, don't use it.
