Need some assistance identifying a SMD diode. It is part of the power output circuit of a Renogy 2000w 12v DC to 230v ac inverter. Renogy have been of no assistance - they seem unable to even identify the model number!! The output circuit was damaged by supplying 230v ac to the OUTPUT plug. So far I have determined that main switch, a couple of output MOSFETs (60N60F01) and associated resistors and diodes were toasted. The SMD resistors I can read (103) but the diodes have either no markings or have been burnt beyond reading even with a magnifying glass.
What information is required to determine what the diodes are? I could supply pictures, but circuit diagram is hard to decipher - I suspect the PCB may be multilayer.
