It should be OK to use a higher PRV, although check the values of V(forward( in the datasheet. Higher currents, OK.
Thanks Again,
I have two Semikron SKN 240/04 Diodes & two SKR of the same value, the SKR I can't use for this.
I have to say that no, I don't really understand about the V(forward) on the datasheet as you mentioned, I used to be an engine builder & my electronics skills are virtually non existant.
I understand a little!
If you had the time to explain from the datasheet attached it won't fall on deaf ears so to speak, I would like to learn more now that I have nothing but time!
I found a place where I can buy the SKN 240/04 diodes at a reasonable price so I wouldn't hesitate to buy four new diodes for this power supply if they are suitable but they may be overkill for this?.
I would like to keep this is in very good working order as it means a lot to me, I wouldn't like to just patch it up roughly.
I can also buy SKN 130/08 Diodes if they are better suited.
Could you have a look at the link provided & see what the best choice of diode is compared to the SKN 100/08 diodes originally fitted to the power supply.
Maximum current draw is 196A.
I understand the thread sizes in the heatsinks may have to be re tapped to suit the new diodes.
If you click on Similar products the whole range of available diodes comes up, five pages or so.
