    Anybody know where I can find a heat sink for this rectifier? It's installed between 2 components so it has to lay flat against the part. maybe one with fins that curl back? thanks

    I'm looking for one that looks exactly like this one that's attached. I went through Digkey and couldn't find it, unless I missed it. The dimensions of the part is 22mm x 19mm

    exactly isn't important
    as long as its dimensions will fit your use
    failing all else, make one ... cut one out of a chunk of aluminium and drill a hole in it

    Yeah, I would find or buy a thick bit of aluminium and cut it to shape by hand.

    I was afraid of that. I haven't been able to find anything on the web. I think device manufacturers who buy those rectifiers in bulk also have companies to custom fabricate the heat sinks for them. I'll have to get a rectangle piece of metal and snip to size then drill a hole through it
