Default Hifonics XX-Cyclops

Need a part # for D5 of the driver board. This driver board has the 4 IR21844S IC's. The cathode of D5 ties to pin 13, anode ties to pin 7.

Marked

It's is the same as D1, D6 and D3, looking at one right now. I have 2 driver boards here at the moment. One has X355, another has X378

So that part # equates to which manufacturer part #, kind of what I'm after.

The reference design/demo board from IR lists this diode as a 600v 1A fast recovery diode and lists the MURS120DICT-ND specifically. The MURS160 would likely be the right part because the 120 is a 200v diode.

The driver board I have here (DWM3640 - similar to the 4-IC board) has an SMA package diode. The MURS160 is in an SMB package which is a bit wider.

The US1J is in the SMA package and may be a better fit on the driver boards.

Bear in mind that I've never had to buy replacements for these so I don't know if the components listed here will work.

The sanken part is 300V 2A fast recovery. I can go with the wider bodied part, plenty of room.

This part was shorted.

I'll order up both versions of that part.

Replaced the bad diode, found an op amp pulling the +15V supply down - replaced that one.

Now the amp shuts down right after the second relay closes. No protect light, just a complete shutdown.

In the time before the relays engage, look at the signal on the output side of the large filter inductors. Do you see audio or do you see a spike of DC?
