      Datasheet is here

      findchips.com or ebay cannot find this part so it looks like you will need an equivalent.

      Searching for "20A DUAL SCHOTTKY BARRIER RECTIFIER" in digikey shows 5 results.

      Unfortunately, I don't know enough about which parameters are critical to the proper operation.

      I will have to defer again to PlainBill or others to fill in. I feel like a pitcher who can go 7 innings, but need the bullpen and closer to finish the game! (Since PlainBill was just watching the baseball game).

        This looks like it may do the trick. VF40100C-E3/4W It's only rated for 100 volts reverse, but I will allow older, wiser heads to verify that.

          Would this be OK?

          http://au.element14.com/taiwan-semic...50v/dp/1453402

          It has the same max voltage rating as the existing one, and the other parameters seem similar as well

            Pardon me for cutting in, I believe this would be another suitable drop-in replacement:

              Sorry, not suitable. In the clear light of day I realized the original part was rated for 200 volts. Also, the output os the supply seems to be 24V, not 12V. I'm really not comfortable recommending a diode array which is rated for less than 200 volts. ALSO, the original had an insulated tab, this one doesn't.

                This meets the original voltage and current ratings, but as far as I can see, the tab is not isolated. This application requires either a device with an insulated tab or an insulation kit must be used.

                  Re: DAC-19M009 dead?

                  Whoops, my bad, missed that the packaging needs to be TO-220AB-FP for full plastic packaging. If full plastic packaging configuration is not available, insulation kits such as this should be fine:

                  http://au.element14.com/multicomp/mk...-220/dp/520214

                  I couldn't find full plastic packaging at the rated 20A 200V schottkys either at element14 or rs-components.

                    Thanks UniT3d, I've put in an order for the diode and for the insulation kit, hopefully it'll arrive this week so shall see soon if it works! (4-5 days shipping time unfortunately)

                      Re: DAC-19M009 dead?

                      Well everyone, the diode arrived, I fitted it with the insulation kit, and everything seems to work fine! Been using the monitor for a couple of hours now Hopefully all the components were correct and nothing else gets damaged

                      Thank you to everyone who helped out, especially retiredcaps for the exhaustive initial tests to narrow down the fault, and to PlainBill for somehow incredibly tracking it down to that one diode! You guys are legends

                        Glad it's working.

                        PLEASE!!! A Legend is a figure from the past. As retiredcaps will confirm, we are very much alive and darn well want to keep it that way!!!

                            Found the MBRF20200CTG, it looks like it is a direct replacement for SB20200FCT as it has an isolated case too. It's available at Digi-Key.
